GiftCardMall review: No delivery, no refund, bad customer service

I recently purchased a gift card through www.giftcardmall.com for a friend of mine. Currently I am using the term "purchased" loosely...technically, as it stands I just gave them money for nothing other then a headache. I bought the card on 10/19, and it supposedly shipped the same day via USPS first class. They claim a potential shipping window of 7-15 days (which already seems a bit excessive). That is clearly posted on their website, though I will admit I assumed it was a "worst case" scenario...I suppose that was my fault for assuming. So we'll move on from that...but, if we start counting from the 20th then it's now been over 21 days since it was ordered, and there have been 18 days that the card could have arrived (because USPS doesn't deliver on Sundays)...if you want to count only business days (Mon-Fri) we're now at 16. I contacted them several times to inquire about the status of the order, and each time I just get a reply quoting the "7-15 day shipping time frame." I haven't asked for anything for free, but simply that they refund the amount I paid, and cancel the gift card (assuming it either never shipped or got lost in the mail). I was just told again that I needed to wait a couple extra days, beyond the shipping time frame, to see if it arrives. It is now approaching a month since I ordered it. I just wanted to send a giftcard as a nice gesture to thank a friend for some recent help...I incorrectly assumed that ordering it online, through this vendor, would be a convenient and quick way to send this gift...lesson learned. I truly hope this is a fluke, and isn't a common experience for other customers, but their response so far makes me wonder. In each of my last few interactions with this company's customer service I requested either a refund, or to be put in contact with a manager who could help me. Realizing that perhaps this was just and accident, I also specifically mentioned that I would prefer to avoid publicly posting about my negative experience, and I'd rather resolve it with them directly. I got the same "bottled" responses, and no real help.They didn't seem to care or have any concern for me, so why should I care if a negative post hurts them? Maybe it will even help someone else...
