Very disappointed

I am very disappointed. Since I have this phone is have complained. Every time a consultant contacts me to solve the problem I get told they will speak to the manager and phone me back and I am still waiting. I get told my contract is nearly finished then I may cancel it then again another call asking if I am happy with everything I complain about the same problem and I do not get assisted. I pay but the service is terrible. You pay for a phone that is supposed to be great for the amount being paid but it's not. It seems like companies may sell bad products and get contracts signed and agreed knowing you may not cancel if you unhappy but they get you fall into there bad products that is not fair.
