Poor service by Standard Bank

I have cancelled my home bond with Standard Bank. After paying excessive amounts towards cancelling and interest it was said that I would receive the interest amounts back after payment and if I continue paying until cancellation, which I did. On cancellation a amount was paid from new bondholder to Standard bank which cover more than the outstanding bond and said over payment was paid back to my account the same day and the account was closed.. The amount that the attorneys paid into my Standard bank bond account was thus paid into a closed account according to Standard bank spokes person and will be paid back to the attorneys. This all happened on the 26 April 2018. Several telephone calls by me and the attorneys were fruitless and every person at customer care have a different story. I am still waiting for my money.
