Extreme Rude Call Centre Agent - Known as Jane

I see there are a lot of reviews on this company and my question is what are they doing about it. a person by the name of Jane keeps on calling me for a Tracker account and is extremely rude and then she put shte phone down she just called me again today and I told her that she is rude and she needs to listen to the customer as well. All I asked was for the tracker contract to be emailed to me as I do not recall signing up with tracker as I have been with Netstar for the last 5 years and she is not accommodating. All she did was quote "pay your account" and put the phone down on me again. As a debt collection company you cannot condone your staff's rudeness, and when you call back there is no answer. Having rude staff does not make people pay their accounts and those call centre agents are in it for the money as they get commission when people pay so the customer service is out by the ****en door.
