Can't close account..... Mr. Price is just loading service fees and won't respond

My account is fully paid up and I would like to close it. I emailed ********** on the 28th of September 2018 enquiring how I go about closing an account. Receiving the following responds: “Please be advised that you have to settle the outstanding balance and request for the account to be closed in store, via email or give us a call. “ I forwarded the proof of payment on 01.10.2018 requesting that the account be closed. Received no responds. On 23 October 2018 I received a new statement with service charges ect. I email ********** again including the previous emails and proof of payment requesting that the account should be closed. Receiving the following reply: Please be advised that there is an outstanding balance of R10.50 on this account. Kindly settle this balance so we can close the account for you. I email again including all prior communication and proof of payment. I received no responds. I emailed again on 01.11.2018 enquiring whether the account has now been closed. I received no responds. 16 November 2018 I received a new statement with another months services fees and insurance.
