POOR SERVICE FROM MIX TELEMATICS AFRICA

I have been receiving sms and email notifications that my account is in arrears, when in fact they have not reflected 2 payments on their statements going back to November 2017. Each time I requested a copy of the outstanding invoice, I received no communication other than to state that I am in arrears. I have sent proof of payment with no response. Last week I spent 3 days reconciling my account with them from August 2017 to May 2020 and notwithstanding numerous emails to their debtors and customer care departments, no one has had the decency to even look at the document which clearly shows where their error occurred (never mind revert to me to try and resolve the matter). I am so very frustrated as both these departments show a disdain for the clients and their incompetence is staggering! They also attempted to repeatedly collect the funds from a company bank account after the contract expired and I entered into a new agreement with a new device in my personal name. I refused to sign a debit order and have been paying via EFT monthly IN ADVANCE since July 2017. I am being left with very little option but to cancel my contract with them.....
