Matrix Tracking appalling service

I have my unit put in approx 2015 and it’s been 10 yrs and the battery in the matrix tracking unit is drained and needed to be replaced,29 September 2025 I called matrix to report this and the customer services rep say my unit is old and needed to be replaced, I then had to sign another contract, and was advised that the technician will contact me, I waited and no one called me, on the 7 October 2025 I called in again to Matrix and nothing was done, I spoke to another customer services rep and he assured me the technician will contact me and install the unit 6 October 2025 between 15h00 and 17h00, the technician gave me a missed call on watsup , with no text or voice message 17h06, I called him back at 17h45 and while I was talking to him he cut the call on me , this is rather sad service levels at the private sector is also been compromised, which the service that I’m paying for, I even sent and Email to the CEO Reitte Botha, and advised her if they don’t come back to me I will go to their competitor to date I had no response , this company is gone to big for a customer who has been with them for over 17yrs and they don’t value their loyal customers , I will not patronize this company going forward and warn all new and existing customers for their appalling service, please guys we as paying customers deserve world class service.
