Abuse of power

During covid i fell behind with my Personal Loan account repayments. During Covid i was put on a temporary layoff. I was unemployed! The same company i worked for also used Standard Bank... when i went back to work my account was already handed over, I've received sheriff letters. I've attended to the letter by written back to the lawyers... My account was then re-handed over to another debt collector DMC, i then committed to repay my account through them of which i did.. They "DMC" Gave me a settlement amount and i agreed! On my last payment my account was taken away from them and Handed to "MBD" with everything happening! I have never received any direct communication regarding the matter... Now i must commit to "MBD" without any proper info or email relating to why i have to carry on like I never had a settlement with "DMC"..... It is quite clear that Standard Bank has lost respect for its banking customers........
