Poor service

I have been a customer for many years of Netstar. After having three cars with their top package, the monitoring unit stopped working. After a few visits to a local branch along with calls to the call centre they could not fix my problem. Subsequently it has been indicated that my fee will increase, for the unit that they cant get to work. When I tried to cancel my contract i was told I my contract was less then the 36 months to waive the fee. I have however been a customer for much longer and hence would expect some form of dispensations, especially in lieu of the faulty unit that i have paid for 12 months for that doesn't work. <br> <br> Truly terrible customer service.
