Closed Account

i had an account with Russells, i paid up my account on the 15th of December and received a paid up letter from JD Group. i was told that my debit would be cancelled when i paid up my account. my account was still debited by Russells in December and i had to reverse the debit from the back. i keep on getting sms from Russells stating that my account is overdue. i do not owe Russells a single cent. I was a good customer and made sure i re-payed their money. they are listing me on credit bureau as a slow payer whereby i do not owe them. This is the worst service ever as you are sent from 1 department to another.
