Complaints about Phone Numbers800-825-####

Received a call to lower my interest rates on credit cards (not from the credit card issuing company). Informed the representative that my number is on the Do Not Call List. Asked representative to remove my number from their system. Rep said, "No, I don't give a f*** about the do not call list." and hung up".

I've had my current phone number 7 months and I immediately started getting calls constantly from 800-825-9472. Morning, noon and in the middle of the night every single day It beeps 5 times, then disconnects. I never answer because I have caller ID. I tried calling the number back but all I get is ear piercing noise. So very annoying especially being awakened in the middle of the night.

Received call from this number indicating I needed to authorize additional amount on my credit card or my flight would be cancelled!!! I have a receipt and have called Delta to verify. Why am I being told 9 hrs after my initial reservation that NOW the airline is not honoring my discount????
