Very angry customer

I have been calling your contact centre about 10 times today without anybody wanting to assist me with my query. I am very upset as you have offered me a free package for a month now I am being billed for it which is something that I am not going to pay for I would like to pay the amount for the package that I was on all these months. I am verg upset and disgusted with the service of your contact centre as everyone that I speak to drops the call on me as soon as I am done giving my details the call drops this is utterly disgusting service as there is many unemployed people that wants to work however your call centre staff does not seem to want to work and this will cause you company to loose customers due to this disgusting service. I just want this problem resolved however there is no one that wants to assist me.
