Bad service received

This is a bad company, I had an arrangement in place and settled my Woolworths account with them in March 2019. The call centre was adamant with calling me everyday with regards to collecting a payment. The last call, I spoke to a consultant and I informed her I made the last payment on the account and that she would email the paid up letter back to woolworths and then the account will be re-instated. I waited for the account to be updated by the credit bureau but no details were submitted. So now my account is in 'limbo' for more than a year, where MBD could've sent the letter to woolworths and sent a copy to me as well and I could have followed up. No response on the telephone line, no response or acknowledgement via email. No follow up call or anything, who is going to do anything about my credit record which has been in further turmoil due to your negligence and incompetence. So don't even dare use this ****, I don't know why Woolworths used your services in the first place.
