Advanta Card - Raised interest rate from 7.00 to 20.99For no reason Advanta raised my interest rate from 7.99 to 20.99. This company is a rip off. Canceled my card, and paid balance in full. Buyer beware! I had used the account for business uses, and charged, and paid between $1, 000 to $2, 000 per month. They still owe me my cash-back money. Think I'll ever see that. I don't think so. I have a great credit rating, and was never late. The rep I talked with had a bad attitude, and left the impression, if you don't like it, leave. I'm 64 years old, and have never had anything like this happen!
