I am actually appalled by the service from Netstar

I am actually appalled by the service from Netstar. I have been with Netstar for almost 9 years now and wow. The experience now is out of the window. My contract with Netstar is R139, however the amount of R204 has been deducted from my account since October or November. I called through and was advised it was Netstar GO. I didn’t sign up for that service nor receive any documentation or information about it. Therefore I want my money back and this is now affecting my tracking system as I had to reverse the debit order in December. Everyone keeps saying they will get back to me when I call through and no one does that. Now you have the nerve to call me telling me I owe R369 for what as I am only supposed to pay R139 to Netstar only.
