Security Checking

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. Further, I have another problem in general and it also applies to Netstar and their legal/financial institutions and that is that when you phone a bank or similar they go through a whole process of doing a security check on the premise that you have contacted the correct person and i agree with this because of all the ***** and ****s going around. However, when they phone you, you are not given the same rights as they want to do a check that you are legit. You don't know them from a bar of soap and they could just be ******** trying to get all your information. They phoned you, surely they should accept that they are speaking the the right person, youi have no security check on the caller in this case. I will not go through that unless they can prove who they are.
