At the end of June ordered a few things from Condorsflight.com. They sell Bersa / Firestorm parts and accessories and I believe I've mentioned them in the past. I received a package from them July 3rd, opened it, and found they'd slapped my shipping label on someone else's package.
Here's where things get good. I e-mailed them back about the mix up at about 2:15 PM on Saturday. Within 15 minutes I had a voicemail from the owner of the company apologizing for the mistake and advising me that he'd get the correct order out to me ASAP. Another 20 minutes passed and I had an e-mail with my updated order info and a new tracking number.
The total time from when I e-mailed them to when my corrected order was out for delivery was roughly 45 minutes. It should be in my hands by the time I get home from work today.
As the title says, that's phenomenal customer service, particularly on a holiday weekend. Even though they screwed up, I'd highly recommend them if you need Bersa / Firestorm stuff.
