Address:	335001
Website:	www.vodafone.in

I got a message from vodafone of offer rs347 in which they were giving me unlimited calling plus 55gb internet for 55days. The next minute i recharged my number with rs347 but got only for 28days. I called customer care but they denied increasing the validity of the pack. The company is doing fraud and is stealing money from the customers. Worst company ever vodafone
