Bad Service and security

I am absolutely disgusted with the contact service I am getting from Netstar. For over 4 months I have been sending them proof of payment for my monthly installments and still not a single person has loaded these onto the system with the result is that they have now handed me over to Norman Bisset and Associates whose personnel at the call centre are just plain rude and put the phone down on me. I wish for once in this country that someone does their job properly. I have yet to see that this situation will be rectified.
