Over deductions and failure to correct

I noticed recently that Netstar has been deducting monthly payments for a vehicle that has been sold some time ago. The cancellation / transfer of the unit was done by an approved Netstar installation centre and the transfer was supposed to have been done to new vehicle and cancelled on the old vehicle. <br> When I queried it on the 6th of December 2014, Zanleigh Padayachee (Customer Service Consultant) rep**** via email (since it is impossible to speak to anyone telephonically - I tried numerous times to phone the customer service department and have never been able to speak to a consultant) that the request has been sent to the cancellations department and the request for refund forwarded to the finance department.<br> At the end of December and January the money was deducted once again. <br> I sent another email on the 3rd of February 2015 and surprise surprise no response to date..... so I guess this is how Altech Netstar operates, extremely disappointed!!!
