I have had an account with Standard bank for years and decided to cut ties with them because being with Standard bank hasn't served me well. I haven't been approved for a home loan, car loan or anything with them so why proceed? After receiving settlement letters the accounts were settled in 2016. Its is 2018 Standard Bank , my accounts have been settled and I have letters from the attorneys proving this fact. Still they have me listed. The attorneys have contacted me and I have been sent the settlement letters promptly. I have been in to the Fourways branch and dropped off the settlement letters. Still they haven't rectified their side. Why am I being harassed and my credit worthiness affected for debt that has long since been settled. Get your house in order Standard Bank. I will never Bank with them again!
