Policy Cancellation not being responded to

I requested a quote with Miway earlier and they provided one and accepted because I felt it was was better opposed to the insurer I was with at the time.

When I got off the call with Miway I got a call from a different insurer and they are saving me a whopping R700 on my premium per month.

I called Miway to cancel and they are telling me that the managers in the retentions department have high call volumes and they will get someone to call me back in 72 hours.

What kind of service is that??? 72 hours is 3 days. The debit order would have already gone through by then. MiWay - please do not find yourselves debiting my account when I have already requested a cancellation What is so difficult???? All I am asking is that the policy gets cancelled.

I requested a call back for obtaining a quote and they called me back in 10 minutes but it takes 72 hours to call back for a cancellation.

Can this policy be cancelled with immediate effect!!!!!!! I don't wanna be escalating this to the Ombudsman or even worse deal with it my way.
