I ordered over $500 worth of discounted Homedepot gift cards at 12% off from GC.com. I received an order confirmation. Apparently I missed their "verification" call from an 800 number. No message, no text, not email requesting verification, nothing. Shortly after that I received an email that they canceled my order. Huh? I checked my GC.com account and saw I mis-entered my billing address by one digit. The cards that were canceled on my first order did not show up on their site or if they did not at 12% anymore (strange). The only cards that were available now were 11% discount. I placed that order and the website said I was BLOCKED. WTF?? I called GC.com the next morning. The rep was useless. I could not get "verified" nor could I get my order. I also emailed them. They emailed me back with some BS about how they pride themselves on their "security". Oh, good for you, you're security is so good you're losing business from a good customer. Congratulations. Ok .... so I took my $3,000 and went to another company and bought discount cards from them with no problems. I'm sure many, many people have used GC.com successfully. You may be very happy if you order from them and not have any problems. But if you miss their ONE phone call or accidentally input any of your information incorrectly, you're likely to get your order canceled and maybe even be blocked. BTW, GC.com sent a final email reply saying my complaint was "resolved". What did that mean? That they WERE NOT going to unblock me and I could never order from them. Nice resolution! Do yourself a favor, buy from another company even if it costs you a whole 1% more.
