Matrix Vehicle Tracking must useless call Center and service

We had been phoning their useless call center for two days now trying to get a unit transferred from one vehicle to another. One useless agent was telling us that we need to take out a new contract and we were transferred to another department just for the call being cut. Phoning back again via cellphone the net agent was telling us we were at the wrong department and we got transferred again. My husband was speaking to a agent and then the call was cut again. Tried twice again today you don't even get to talk to an agent and your us cut. What if you had an emergency. Totally useless
