Dissatisfied service of Nestar

I am so disappointed in the way my query was handled by Netstar staff. I called in on the 16th of November to query a cancellation and was told by the agent who assisted me that he could not assist me with my query and that I needed to call the finance department to make the arrangement if i wanted to cancel my tracker unit. He told me the amount was R2656.07. I said i would pay this in 2 instalments hence i was referred to the financial department .I understood it was within the 36 months and there would be a fee I needed to pay. To my dismay I see the payment come off my account for the full amount, even after he said he could not assist me. I was told to call them after the 26th of November and the 16th fell on Sunday the admin/accounts are closed and so who gave them the instruction to cancel the contract. I have tried to call Thabo the manager and he seems to be playing hide and seek with me, I was told he was in a meeting this morning and would call me back that was 9.30 am and it is not 12.33 am and I tried calling again and again and still I cannot get through to them. What they take my money and hide from me now, is this the service I get from Netstar now. I have been a faithful member for years. Seems dogs are more loyal now days.
