CARTRACK DOESN'T CARE

So on the 9th of July 2020 I bought my 2019 Opel Crossland...on the 10th of July 2020 Cartrack came to install the tracking device on me vehicle. After 2&1/2 hours it was finally fitted but my vehicle doesn't start or unlock from the remote key??? After disconnecting it the vehicle started but still not unlocking. A Tech from JHB was called out to "fix" the car,but he can't either! I left for my house at 19:00 that night after installation started 13:30 that afternoon! I had to leave my vehicle in the garage as the insurance doesn't cover if ****** due to key not working & tracking device being disconnected! On Monday 13 July 2020 we had to take the vehicle to Opel ourselves. Opel submitted a quote and findings on the breakage. Numerous phone calls to tell me I have to pay R870 for reinstallation, I finally decided to end the contract and had to pay R2525.28 in order for them to stop calling me! Still no answer on my vehicle at Opel! After finally giving up I spoke to Lauren at headoffice which ensured me that the payment will only be made today 22.07.2020!(another week without my new car) On 22.07.2020 i asked for proof of payment which after several hours only Lauren informed me that it hasn't been paid they are waiting for a report??? The tech who installed the unit should be responsible for writing his report seeing that he is not capable of installing units in vehicles!!!!! So yet again week no 2 without my vehicle & no support on the inconvenience of how I get my children to school or me getting to work! PLEASE PEOPLE OF THE PUBLIC, BE WARNED! THEIR NEW FB AD SAYS FREE INSTALLATION, IT WILL COST YOU YOUR VEHICLE AND YOU WILL BE OFF WORSE THAN BEFORE YOU HAD THAT DEVICE!!!!
