Very first credit card I had was a Visa card in 1979 -1980. It was only good for $1K. I maxed it out and stopped making payments.
Fast forward to 1988 and I found out that $1K debt and non-payment was still on my credit report.
I wrote Visa a letter asking how I could make it right.
Visa replied they had no record of the account and as far as they were concerned I didn't owe them anything.
1988 was before email, so I had a hard copy letter from Visa via snail mail that basically said they didn't know what I was talking about.
SOooo ... I was in the military and stationed in Norfolk Virginia in '88. There was a
TRW Credit Services office in Norfolk. You could walk into their office and for something like a $10 fee, they would sit down and review everything associated with your credit reports.
I had the letter from Visa in hand when I entered that office. The lady that helped me was married to a military guy and I was military and I think she did everything she could to help me out. Anyway, since Visa didn't know what I was talking about and had no record of my ever having a Visa account ... right there on the spot, the lady was able to erase that Visa record of debt and non-payment from the credit reports.
That afternoon when I left that office, my credit reports were showing that I had the highest credit rating possible. T1 or something like that, whatever tables they used to rate credit back then.
Then one day many years later, I found myself with just north of $23K on a credit card and the card limit at the time was $24K. So I'd almost maxed it out. Now for some, maybe coming up with $23K is minor stuff, but at the time, I had to sacrifice a bit, plan and stick to the plan to pay that $23K off. It took a couple of years.
I still have that Platinum Visa Card and the credit limit is now $29K without me ever asking them to raise or lower the limit. I pay it off completely each and every month, so don't incur interest. And my credit score fluctuates between about 820 and 842. I've briefly seen 845 and 848 from time to time. And because of my credit history and that score, I have the lowest rates offered on any card from my financial institution.
I do use that credit card for online shopping because I don't want my debit card number on the webs. Locally I always use the debit card. I very seldom use cash anymore.
