SBSA Home Loans Awful customer services

Looking at the -74 NPS Score I don't have much hope but here goes. I sold my house in December 2020 and all documents, land registry etc. were all closed off on the 21st of December 2020 but Standard Bank (Home Insurance) still carried on taking home insurance off my Standard Bank account until I eventually got hold of someone and forced a cancellation in April 2021. I'm owed money by Standard Bank and logged a call in April 2021 to get the money refunded to me but they have ignored, made excuses and in my last call on the 22nd of June asked me to provide proof of transfer which is ridiculous seeing as the house was bought with a mortgage from SBSA and CLOSED with them as well. I'm now being ignored while having chased this on numerous occasions.

Shame on you Standard Bank, treating someone who's been a customer since 1988 like this. When it's the other way around you would be quick to charge interest, I wonder if I will get interest back once you actually pay the money you ********ly deducted from my account back to me.
