Bad service

I had motor vehicle warranty with mvia and never missed a payment.I called in to cancel my policy on the 14th of December 2022 and the consultant told me that I needed to send an email . I sent an email in order to cancel my policy ,only to find out they are still deducting my premiums in October 2024 . I called in and alerted them and they asked me to send through an affidavit stating that I will not be reversing any of my premiums until they are done with their investigation .I did all of that and still haven’t received any feedback from them . I called in December and they said they are still busy . Today no one is answering their calls . I would not recommend Mvia as they have sent me from pillar to post about my refund and I was very loyal customer
