web bank pearl mastercard canceling card for no reason beaverton, Oregon

Ive had a web bank pearl master card with a 325 dollar limit. I use it and pay the balance in full each month. I received a letter stating they closed my account.I think this will drop my credit score.I called customer service and got a chowder head on the phone that was no help.  I hope if she has a credit card it gets cancelled to.  Its my belief im not the only one that got a letter dated Nov. 16  2009.  I dont care if they cancel me but i dont want my credit score to drop 5 to 10 points. because i didnt breach the contract on my end.If they cant let me use 300 of their dollars each month and get paid back on time with intrest they shouldnt be in business. I also think they should have more compentent customer service personel not just some a*s hole that reads a pre printed letter off a computer screen, and then ask if i wanted to pay my bill infull. THey can kiss my a** ill pay them the minimum each month till my bill is paid off.I hope you web bank idiots go out of business and all your employees are walking the unemployment line the day before Christmas
