Poor non existent service delivery for business clients

I logged for a deinstall and reinstall on the 26th March, was debited R870 on the 31st March, nothing happened after that, I had to call in and ask for the install to he done. Was planned and arranged for Saturday the 11th at 8am, confirmation even done Friday afternoon for Saturday 8am, technician never showed. Complained last Saturday, asked for someone to contact me to resolve giving Cartrack an opportunity to right the wrong, never heard from Cartrack again. Last night I was debited AGAIN for another deinstall and reinstall. I have since emailed, called and spoken to various team leaders for a total of 1 hour, and i am still waiting for someone to call me and explain why i continue to be debited for a service i am not receiving. Ian Holman even escalated to the retentions department to call me for cancellation so i can move to another company, retentions department also can't be bothered to call back.
