Refund not processed

Called Motorvap on the 20 Feb 2023 to book my car in for service and was told that my contract lapsed however they have been deducting for year still. I was told by the consultant that the retentions department will give me a call to arrange a refund. on 22 March I followed up coz no one had called me, no response. On the 29 March I called and was told that I need to do an affidavit indicating that I will not reverse the payments. I found this ridiculous considering that they have deducted for a year and suddenly need an affidavit for them to refund me. The consultant I spoke to was very rude telling me that the onus was on me to call them when my contract lapsed (revolting). Does not it have to automatically terminate and they call me to tell me that its coming to an end? who keeps track of expiry dates of all contracts their contracts, especially these telephonic ones mxm. I did the affidavit and sent it through on the 12 April, followed up on the 4 May and there was no response. Followed up again on the 31 May and still no response. And again today the 8 June 2023. I want my refund for the 12 month deductions made. This is really annoying to be sending emails and calling for my money to be refunded. The next step will be send this to the Ombudsman.
