Bad service

It is disappointing to receive bad service from a well-known company. Netstar failed to honour our agreement of debiting premiums from my account, i have contact then several times and was always told that everything is up to date. i later received a call advising me that my account is in arrears , I asked for my premium to be debited on the 20th of every month going forward however it never happened. I have been calling Netstar from November 2014 to get this sorted and to date it still not sorted, I called them for follow up and one of the Supervisor by the name of Deshni Pillay had the guts to tell me that they are not offering free service yet I called . I regret the day I choose NETSTAR , Deshni and I didn't reach an agreement and I then asked to speak to her manager or the person she is reporting in to , I was shocked to receive a phone call from a consultant who is reporting in to Deshni because my expectation was that I will get someone who will assist or rather sort out my so long query.
