I used to Postpaid idea, then I left this service after seven month later. becos I found in every bills they had some mistakes.
Every month month the bill amount increasing. when I complained they take time to next bill. and every time I found the increase wrong amount in bill becos of the vas-services. and process are very slow. one time I was remember I call to police and I had to take help them. then they are said sorry for that refund my all money.
