Shocking Service

I have never come across such shocking (lack of service) from any supplier ever. I have tried numerous times to phone them, either they simply do not answer ones calls or you get through & remain on hold for 20 minutes or more, I have been trying to cancel my policy since begining of March 2022, I eventually emailed them, no response, I have emailed numerous times, sometimes I get a case number, yesterday they said they will be handing me over for non-payment I am at my wits end with them. Our sales managers car was ******, the tracking device from Mix Telematics didn't work so he was unable to trace his vehicle - shocking!!!
