Chase - Credit Card Review

I had Chase, years ago and was so displeased with their pratices I paid the card off and closed the account.

Recently, my previous credit card company was purchased by Chase, much to my dismay. Not wanting to deal with Chase again, I paid off my the balance as stated.  They charged interest for the days that the card held a balance the previous month.  When I called to see what was going on, I got an extremely rude representative.  No one offered any solution, except "pay a little extra and we'll send you a check for the amount that you over pay."

Once I get everything settled, I will be closing this account as well and I have had this card for over 10 years.  Chase has had it for only 6 months. Chase is by far one of the worst Credit Card companies I have ever delt with.
