Contract Cancelled and No installation on new contract

Bought a bakkie from Ford Hatfield in Dec with a Netstar tracking unit fitted. Had no issues. Noticed in Feb that my app wasn't updating my vehicle. Contacted the call centre and found out my contract was cancelled. I asked them to investigate as I haven't cancelled the contract. No one came back to me. Called the call centre again a week later as I was uneasy without a tracking unit in my car-went through everything again. I was promised that the manager will call me back that same day. I'm still waiting...Out of frustration I opted to sign up online (at a higher tariff that my previous contract was). Went through everything and after a lot of hassle managed to book a fitment online on the 17th (took a almost 2 weeks wait). I've added a note that I do still have the tracking unit in my car - but no one has bothered to call me or pitch for the installation or cancel the installation for that matter. No what do I do Netstar? You don't call, you cancel contracts at your own will and don't install new contracts. I guess you don't need customers.
