Bad experience

i have been with Beame- mix telematics for many years recently i got retrenched so i sold my SUV cancelled the same day my vehicle was sold, 3 months down the line they were still debiting my account. Made numerous accounts the consultants hear the story but nothing is done about it. Eventually cancelled my 2nd vehicle after writing a frustrating email to them. i had 3 calls logged with case numbers no one responds. Now they sent me an sms to say my accounts is in arrears. Best thing to do is cancell the debit order with your bank and reverse the last 2 payments. very bad service
