Billed for two units whilst I have only one unit in my car

I have upgraded my tracking device from Beame to MX2 on 30 March 2022. The person who helped me with the process didn't cancel the Beame unit, as a result I was billed two units, even though I only have one unit in my car.

On the 3 of May 2022, I called the customer care department (ref ***9) requesting for the Beame unit to be canceled together with the debit order of R74,99. The lady who helped me with the cancellation stated that my account will be refunded with the debited amount and that didn't happen. On 1st of June 2022, I was billed again for two units. I tried with no success to contact accounts department. I contact customer care department again today this morning (ref ***6) and the consultant promised to escalate my query to accounts department, no one has called me back.

Please cancel my monthly subscription! Mix Telematics staff members are *********** and inefficient. Accounts department doesn't pick up the calls.

Terrible and pathetic service ever!!!
