How to Get a Lower Interest Rate on a Credit Card

on 11/8/2007 my credit card company has raised my interest rate so high that it will be impossilble to ever pay it down .i have lots of credit because of my spotless payment history.and i use my credit for business purposses.but im scared that they will force me into ruining my credit .with their outrages interest rates. i have called them told them ask them why they would do such a thing to a good customer. they say your debt is to high your a risk my score 693 average risk . is there anything i can do

on 6/30/2006 I had a decent sized balance on one of my credit cards. I paid it off in one big payment. The next statement sent to me for the card informed me that I was being given a lower interest rate. I suppose they thought I was trying to get rid of the card and wanted to talk me out of it.

on 11/22/2005 When requesting card cancelation, I have been offered much lower rates and very low transfer rates with no fees to keep me as a cardholder.
