Very bad service

Do not use this place. i never received my contract on e-email they never. On the day of accepting the contract they phoned me to make a booking to fit the unit 24/03/2023 the person never arrived I had to phone Car Track to find out what's going on then they told me they can come and install on Tuesday 28/03/2023. I did ask please make it for the Monday the 27/03/2023 they never phoned me back . so on Monday i phone again 27/03/2023 no booking has been made and they can book me for Wednesday 29/03/2023. Then i had enough of this service i am receiving from this place and i cancelled everything. now the this is they are trying to phone me every 5 min the phone rings for 1 sec and then they put the phone down. Please do not waist your time with this place Phone Tracker they are professional.
