Standard Bank does not know what they are doing

I had 3 loan accounts with the that had credit protection which I paid monthly. When it came time to claim I had no problems and others accounts were settled by their insurance company. However Standard bank administration department does not see this as settled and has decided to harass me up to 10 times per day and as their agents start going into the accounts they say sorry we see it has been settled it is not us calling you its our system. It will take our administration office 7 working days to fix their error. Now its been 7 days and what has their administration done they have now handed me over to their legal/collections agency who now calls me at 7am every morning now what Standard Bank what now
