Poor and unprofessional service

Hi

I had a Absa personal loan that was in arrears and was handed over to MBD. I settled the outstanding balance in June 2022. Over the past two and half years I have received numerous letters(emails) from MBD and even had the sheriff of the court knocking on my door with regards to this. The most recent email was sent last night. I have sent the proof of payment as well as a letter from Absa stating that the account is up to date. Can you please resolve this matter and stop harassing me with your emails? Over the last 2 years i have been back and forth communicating but it seems every time it comes back. I am not going to name and shame the people that i dealt with hence I would like a letter confirming that I will not receive these threatening emails anymore.
