Worst Service

I have cancelled the building contract with the developer which went well, Then i had to withdraw from my standardbank bond before the bond is registered to my name which went well. but now Betterlife is driving me crazy because they are not cancelling the bond protection i have with them, They are asking for the cancellation letter from standard bank whereas i and the attorneys told them that there is no cancellation letter from the bank because the bond was not yet registered to my name, So the account has been cancelled from Standardbank. I have been paying for the bond protection plan in the last six months. but now i am struggling to get it cancelled and get my refund. all i want is to get my bond protection cancelled because there is no bond protected and get my money back
