I had a period some years back of credit card debt - screwed me up badly. But, I worked it out, paid it off, and now have one CC with a limited credit amount, which I can keep paid off. I check the account daily via online, that really helps. The paper notices are always at least two weeks out of date, so easy to lose track......
A couple times the CC company tried to 'reward' me by upping my credit limit - I call them and have them put it back to the lower amount. Have had the CC number used illegally a few times (twice via PayPal, I avoid them like the plague now!), but he company is quick to get it made right. Have gotten my money back after filing fraud report and getting new card.
Had a smaller CC once, with a very limited credit limit - they allowed a foreign entity to suck it dry at twice the limit amount, and would NOT help - I believe they were complicit in the crime - AVOID First Premier Bank at all costs! They are crooks!
I keep a very close watch on my CC account nowadays. I do not want to get those incessant collector calls again! They even call family with NO connection to the problem - that is embarrassing and should be a crime itself.
I have had a good credit rating for a few years now, and have no problem purchasing vehicles, etc. It took years of hard work, and I'll not lose it again.
