Poor service

After switching my insurance, I am required to do a unit upgrade. I contacted Cartrack two days ago and made a request for a unit upgrade, to date I have not heard from them. I phoned again this morning and I was told that an urgent email escalation has been sent to the insurance department. I am sitting with a car that cannot be used until this upgrade is done, email communication in 2025 is not going to be a quick way of getting anything done. Cartrack, please step your game up. Email and text communications do not guarantee receipt and speedy resolution, I am stuck and not happy with this. Every department has to have a telephone number, this cannot be. Really!
