TFG not to be trusted!!!

Good day I paid up my account at Sportscene in 2019.There records even shows it was paid up at the branch in Cavendish Square Claremont. For the last 3months I have been receiving constant phone calls that I owe them when I have requested for my account to be closed. They have not done there work in the accounts department and now they harassing me for money claiming I owe. It has now affected my credit scoring which cannot be left this way as they are *****ing from there customers. This will not be left at this until my name is cleared for there mess up. How many other people are being ****** daily and blindly in this manner. Imagine after two years they are now trying to claim money!!!!
