Fidelity poor service

I have been an Amber Connect customer since 2019. Recently I have been experiencing problems with the tracker unit in my car as it does not give me notifications and the unit beeps when I drive. I've contacted Fidelity on several occasions and was given 7 different numbers to call. All these numbers are either unanswered or does not exist. I have contacted the service provider via SOS and they are also not able to assist me.This is ultimately a poor reflection of Fidelity services and is totally unacceptable.
