inconsistent communication

My Edgars account was handed over to MBD and I called them on 14/02/2020 to ask fo a settlement letter and that was sent to me on the same day and have been going up and down with them as they were not debiting my account, finally on 18/02/2020 they provided me with banking details and i made the EFT payment to the FNB account provided and now when i request a paid up letter they are reffering me to Edgars as the account number they provided was for Edgars and not theirs, I went to Jet on 19/02/2020 and they called the Head Office and got a reference number *** saying i will get the paid up letter within 15 minutes and to date I'm still waiting. Called Edgars again today I got another reference number as they still need to contact MBD who had offered me a discount on the outstanding balance who must now zero the account and they cannot give me a turnaround time and my life is now stuck as i cannot have my bureau updated as they are all sending me from pillar to post
