Very upset customer

I took out a contract with this company last year march. They have been debiting every month from my account how ever i have just recently notice that they are updating my paymen history incorrectly on Experian. Blue label connect has been updating that i have not paid since last year 2019 nov. Which is not true the amount goes off every month. I have tried to call the call centre numerous time and everytime i am told that it is escalated to the relevent department And someone will be in contact with me. Its been more then 3 months no one has connected me to get resolved and it is affecting my crediting rating and credit score. I cant wait for my contract to end so that i can cancel my damn contract with this **** of a company. I will never recommend this company to anyone
