Poor service

I just bought a vehicle then SAU insurance company offered me a service with me. We agreed initially, however, the following day some lady phoned me with same company saying that the value of my vehicle is high Njabulo the service advisor from SAI was under quote me. I wrote an email to Njabulo to cancel the deal if the keep on change the deal. There was no response from Njabulo till today. I sent several emails regarding my refund, I made it clear before they deduct the money that they must stop it with immediate effect. Up to date no indication from them when are they going to reimburse my R850 and I want my money. This is terrible service ever in my life and I don't wish anyone that I know to join this insurance company.
