My experience with CSMC has been nothing short of outstanding. Yes, I have purchased some guns from them, but I visited and contacted them frequently before I ever purchased a gun from them and always received the same great CS. In their defense, I know that they are under-staffed and most have no idea how many calls they field in a day. I have had three factory tours, and their phones ring non-stop and everyone wants to talk with Tony or Lou. We all want to be treated like we are the only customer, but many times unfortunately it is not possible in this crazy, hectic business world.
Oddly enough, my experience is similar to what Kevin describes above. I'm somewhat local, being from Massachusetts, and have spoken with Adam on the phone several times while ordering my RBL-12. I was planning to be in the Hartford, Ct, area today so scheduled an appointment with Adam this morning to discuss some work I'd like to have done on my RBL. He was very friendly and polite and let me poke around their show room for a while and play with an A-10 they had on hand.
I have absolutely had nothing but pleasant experiences with CSMC. But then again, I tend to be very polite and perhaps that helps. Despite the adage that the "customer is always right," some in business firmly believe in sending certain clientele to their competitors, with good reason. We shouldn't need to earn a company's customer service but should not be rude and unreasonable customers either.
