Poor or no service from Max Telematrics

If I could give a zero star rating I would have! The first email I sent to their customer care centre on 12 July 2022 informing them that I purchased a new vehicle after being with them since 2016, I wished to have the unit transferred to my new vehicle. On the 15th July 2022 I contacted Matrix via the Facebook messenger to inform you that I had sold the previous vehicle that had a Beame unit installed, I requested that the unit be transferred to my new vehicle. A case number was logged (***0). Later the same day I was informed that a sales consultant would contact me. On 18th July 2022 nothing had happened, I threatened to cancel my contract. On Monday 18th a sales consultant contacted me, a new contract was initiated and I was informed that a technician would contact me the next day for the installation and the t the installation centre in Klerksdorp had closed. I reminded Matrix every day via face book messenger (that is the only platform that receives answers) that the unit had not been installed, I had to phone several times to find out what was happening, every time I called I was placed on hold for 30 minutes at a time, Thursday afternoon I called and spoke to an Indian gentleman who informed me that the unit would be installed, today Friday I called again, 23 minutes later I was informed that the unit would be installed on Monday the 25th July 2022.I have placed a suspension on the stop order and wish to cancel the contract with immediate effect . I have forwarded the same mail to the MD and also received no response. On Monday 25th July I received a call from a lady informing me that I should take the vehicle to a place in Klerksdorp for installation, I could not as I was on my way on holiday. I have recently received an invoice for the contract I cancelled on the 18th July 2022.
