Disgusting service

Am very disgusted by the service of Cartrack...I have notified themail that am buying a new and i would like them to take out the old unit from my old car and put in my new....arrangements were made paymentsome were scheduled a week later they still haven't installed it and I was told they can't get hold of the person who was supposed to do the installation.Cartrack company is full of nonsense and they only care about money.The consultant 's name is Ruth.This company says that if one doesn't show up on the appointment they charge you you that...now my question here is if they play a no show on a client what r they going to for the client...because right now I want nothing to do with it just want to terminate the contract.
