CallingCards.com Bait and Switch routine Nationwide

My wife calls Thailand frequently from the USA, her old card had run out, I found this one on line. As it was new to me I didn't want to buy a lot of airtime, so glad I didn't. What a scam, the WorldCalls card that I had purchased advertised calls to Thailand at a very good rate (1.9 cents a minute) and offered 526 mins. for a $10.00 card. As soon as I got the phone set up to call I checked the minutes and found they had dropped mysteriously to 150 mins! That is without any calls, after making a call the minutes were almost gone, I actually could have called cheaper on a landline. After repeated phone calls to the company and numerous emails I gave up, it wasn't worth my time. Buyer beware, horrible company
