Standard band home loan

Am not happy with the the service I received from standard Bank, I had a home loan with them the house was sold 2018 after standard bank Said we have a shortfall of R 58 000 , I tried to dispute this matter but I didn’t win then after they handed over the account to ITC without our knowledge.. last year got divorced and my ex-wife agreed to be liable for the account so she paid it up January, she asked standard bank to send the settlement letter/ proof that this account has been paid.

since January standard Bank never sent the letter so that we clear our name with ITC, now am receiving calls from DCM Dept Management say that am owning R 58 000 , I sent them an email they never Standard Bank is full of fraud.ref 530698730
