Agents are very rude on the phone

Hello Peter, ever since i have started using homechoice i have never got a good agent call me, they are always rude and shout at me over the phone, they never ever tell me if the calls are recorded. The last agent i spoke to said if i dont pay she will make sure that they call me the whole day and she hung up the phone, i have been asking them to send me my statement via email but they always say that they will send it in two days but never do. I am really not happy with the poor service that they give to us client
