Standard Bank Homeloan - poor service and not forthcoming information

I have been dealing with the homeloan department at Standard Bank regarding an existing account, boy I must say it is extremely frustrating because there’s no information nor advice offered on what to do when settling an account. Oh! By the way I also learnt that even if I’ve settled the owing amount the bank continues charging interest as long as the account is still open. Basically will charge interest on the insurance premium since I initially decided to let it continue with Standard Bank. That sends me to go shopping elsewhere.
