I placed an order with Infinite Arms back on the morning of August 2, and I've been having trouble with it ever since. I placed the order and submitted payment, which processed through my bank on August 3 (a Wednesday). I was headed out of town on Thursday anyway, so I didn't think about the order until I got back on Monday and it had not arrived. I looked up the order status on their site, and it was listed as "processing." Since Tuesday was a full week after placing the order, I called then to try to check the status. My call wasn't answered, so I left a message. I understand small shops, so I didn't think much about it. Later in the day, I sent a follow up e-mail also. Two days later (second Thursday after the order was placed), I sent a second e-mail, and I began calling with some frequency (4-6 times daily). Never an answer to the phone, and no response of any kind. Finally, on Sunday the 14th--12 days after the order was placed--I received a return phone call (from a different phone number). I was told that gentleman I was speaking to (owner?) had been out of town with a family emergency and that his main employee had done nothing while he was gone. He could tell from my voicemails that I was getting somewhat agitated, so he asked if I wanted a refund or if I still wanted my order. I told him to please send the order, and he said it would ship out first thing Monday (August 15). I should then have it in my hands on Wednesday or Thursday (17th or 18th). He promised an e-mail with tracking data. When I still had not received that e-mail on Tuesday afternoon, I called the shop. For the first time, the phone was answered. The guy on the phone seemed genuinely helpful, but he said it would take him a few minutes to look up details about my order. He took my phone number and promised to call me back in 10 minutes. I called them back after 20 and again numerous times throughout that day and the next, but no one picked up the phone again. I left messages at both phone numbers I now have from them (the second of which is definitely a cell phone number), but nothing came of it. Thursday came around, and I still hadn’t received the order, I hadn't even gotten a shipping confirmation, and my account on their site still showed the order as "processing." They still hadn't shipped the order 16 days later, five days after directly promising to ship it out "first thing in the morning." On Friday, August 19 (17 days after the order was placed), I got a phone call. They claimed that it had shipped out on Wednesday (the 17th). I did not get the shipping confirmation e-mail, but he said they've been having some trouble with that (software related, he claimed). He said that he would text me the tracking number in 15 minutes or so. That never happened. I called again on Monday the 22nd. I gave him my order number, and he said it would take him a few minutes to look it up. He promised to call back in 5 minutes. (This may have been the same guy who never called me back before; I couldn’t remember the voice.) I wasn’t keen on letting him off the phone, but I didn’t have time to just hang on there for as long it was going to take him. No call back. No answer when I called them. Again. But 3 hours later, I got a shipping-confirmation e-mail. Yeah, when they claimed that it had already shipped, it was outright false. Now, it’s not a big deal, but I like UPS as a delivery company. Their driver is the most courteous of all who bring stuff here, and their tracking system is by far the best. I choose UPS shipping whenever possible, often even choosing a different supplier if they only ship with someone else. It’s been long enough that I really don’t remember if I got to choose UPS or if that’s just who they said would ship it, but you can see on my order that it claims it will be shipped by UPS in two spots. It was shipped USPS priority, which is a slower, cheaper service. Not what I paid for. Finally, on August 24 (22 days after I placed the order), I received a package. It was drop-shipped from another supplier, and apparently communication between the two is poor. Here is the description of the item I actually ordered (emphasis added): Here is a picture of what I actually received: As you can see from the description, I was expecting a railed gas block, not the A2 that I received. I don’t really care that much, but it’s just another example of disregard for customer service. At this point, I have not even mounted this upper onto my lower receiver. If there is anything wrong with it, I'm going to deal with the supplier directly. Still, I am quite comfortable stating that I would not recommend Infinite Arms to anyone.
