Cartrack poor service

I recently sold my vehicle which had a tracking unit installed by Cartrack. I contacted them and asked for a removal and installation on the new car I’ve been waiting for feedback for installation on the new vehicle and I was told there’s a shortage of technicians and they will only be able to install the new device the following month on the new car, how is that even possible while I won’t be covered if anything where to happen to the new car I got. Honestly poor service we are living in a high crime rate country and they not taking their clients serious enough.
