Activates of Hollad Insurance without my authority.

I Mmakoribane Lyvia Maitse. I am not happy with standard bank as a whole. Standard bank activated Hollad insurance for my Vehicle without my authority. I was debited R1 757.00 for unknown insurance . I have a car insurance with Miway. Now I am paying 2 insurance for 1 car.when I requested a refund Standard bank send me from pillar to post. I am going to eat black Christmas because of standard bank, my other debit order pounced due to insufficient fund in my account. I did not sign an agreement with Hollad insurance. I want my money today. I went to standard branch on Monday morning they did not help me. Standard bank is a **** bank.
