i had purchased nokia c7 from phones4u on 17/01/2011. the real cost of the contract is 25/ month but they charged 40.85/month to me .and also inform me that am having unlimited landline .so i have used international calling card but when the bill cames its totally charged for my calling card .when i talked with phones4u they are not accepting there mistakes also my friend took the same c7 nokia for 25/month with the same scheme .so am very unhappy with this contract and the staffs of phones4u (hounslow branch).please refer me what can i do for the next step .its a burden for me to pay for the huge bill .
