ACCOUNT CLOSURE AND PAID UP LETTER

I finally spoke to Noluthando Ndlovu and she told me that the account is not settled because the never gave me a settlement letter. I phoned in to request a settlement letter before settling the account on the 2 October 2020 and even today the lady I spoke to never sent me the requested letter. on the 6th/10/2020 I phoned in for a paid up letter, the consultant confirmed that she saw the payment and yes she will then send the paid-up letter and for someone to ask me 30 days later where I got the settlement amount from is very disrespectful because it just shows how *********** your staff is AND CLEARLY THEY DO NOT ADD ANY NOTES ON THEIR SYSTEMS AFTER COMMUNICATING WITH CLIENTS. I was told yesterday and today that a senior personnel will call me with regards to this query and I am still waiting for call. I was told to send an email yesterday and I am still waiting for feedback. I am wondering what is the best communication to get through to ADRS because even the company that handed me over to them cannot help me. I have been paying this account via Rochester statements, not even a single communication from ADRS on paper about how much is outstanding and today someone wants to tell this like they did not give me a settlement amount. I paid this account the very same day with an FNB loan account I did not go through this, instate when I phoned into FNB they said the account will automatically close itself since paid off. Bare in mind I settled it without a settlement letter too.
