NETSTAR HARRASSMENT NEVER ENDS - INCOMPETENCE IS SUPREME THOUGH

When I bought a new car, I was told is fitted with Netstar and I just need to activate it by a call which i did. The car had specification problems and i had the car returned to the dealer. However, Netstar never stopped billing me for this car. When i enquired they told me i had to do the cancellation in writing, which i did and settled all the invoices to that date. Netstar wouldn't stop billing even after the cancellation. They started harassing me and when i checked with them, somebody at Netstar did not capture my cancellation (SUPRISE, SUPRISE!!), they demanded i pay the bills and send another cancellation, i reluctantly agreed, paid off the bills again and warned them if they don't capture the second cancellation i will no longer pay for any subsequent bills. Netstar with stunning incompetence again did not capture the cancellation it would seem, and kept on billing me some more. I decided to speak to one of their manager about this Steven Thomas, a Credit Controller, he promised to sort it out. that was the last i heard of him, from there i was getting none ending harassment calls from Creditworx who boastfully tell me they will harass me till i concede to pay up. I stood my ground, the HARRASSMENT BY NETSTAR AND CREDITWORX CONTINUES. It's been 2 year now. To all consumers, avoid NETSTER at all cost if you can.
