For various reasons, I am currently taking steps to increase my credit score, one of the steps being to increase my credit card limit.
The last time I had a credit card was around 10 years ago. I found it to be harmful to my then financial situation, so I paid it off in full and stopped using it (I think I cut it up and closed the account).
So I can't understand why it states in my credit report:
Credit cards (1)
£0
Total credit limit = £300
Does this mean my account is still open?
Would I have to open an account with the same company to increase my credit limit?
What is the best way to move forward with the goal in mind, what is my next step?
I wanted to ask here because I don't trust information from credit card companies, especially the company I had an account with.
