Extreme level of incompetency

I took an account with Bradlows in August 2020 and 2 weeks later I settled them. I have since then requesting my paid up letter but none. Last week Thursday the 24th September 2020, a month later after having settled my account I receive a statement from Bradlows that says my account will be debited on the 28th September 2020. I was very upset with this company. I sent an email to their head office, the email was sent to a lady by the name Helenna. In my email i also requested my paid up letter to be sent to me ASAP. I also visited the store where I got my products/items from and they assured me that the account is closed.

Sunday evening the 27th September I get a paid up letter from Bradlows and I am excited that the matter is settled and resolved. to my surprise i wake up this morning to a debit order from Bradlows.

I have never been this angry as this is tempering with my account. important debit orders will bounce now as a result of Bradlows incompetency. This cost me a lot of money to reverse and fees charged for bouncing debit order.

The acknowledge that I have paid up my account however still deduct money from my account. What nonsense is this.

This is tempering with my credit score having to have late payments and reversing debit orders. How the hell such incompetency exists in a huge company like this.

Please help me get this sorted and Bradlows removed from my profile.
