IDT won't go away
CLEAWATER, FLORIDA -- I used IDT for long distance on my land-line phone for years. We recently moved and decided to get rid of our land line (just use cell service). So I disconnected my land line and cancelled my service with IDT in February, 2007. Three months later, I received a bill from IDT for service provided in April, 2007, to my cancelled number. WTF? I called and was told they never received my cancellation, even though I mailed it as a letter with my final bill (they managed to cash the check but not to cancel my service). After an argument, they agreed to cancel the account but I had to pay the bogus April charges. Three months later, I received ANOTHER bill from IDT for service provided during July, 2007. This time, the bill showed the "service" was for a telephone number I haven't had since the LAST time I moved 8 years ago! WTF?
I called IDT again and explained they're charging for service to a phone number that hasn't existed in 12 years. They promised to fix the problem once again. But once again, three months later, I received ANOTHER bill from IDT for service provided in October, 2007, to the 12-year-old phone number. This time I filed a complaint with the Federal Trade Commission and ignored the IDT bill. About two months later, I received a copy of a response to the FTC from IDT's legal department. It basically said they would fix the problem (my question, "When?") but that it was somehow my fault! In February of 2008, I received yet ANOTHER bill from IDT for service during December, 2007, to my non-existent 12-year-old telephone number. I ignored it.
Moral of the story: You cannot cancel IDT. Once you have them, you're stuck with them! Also, their customer service people were very rude, each and every time I spoke to them.
