Aircel always provides customer friendly. Once Rs 50 had been deducted from my main balance without any reason. I just called then to the customer care and asked them to do a proper enquiry of why my Rs 50 had been deducted. They just took 2 hours to investigate and refund my balance. But this happens with most of the consumers using leading mobile operators. But they will refuse you to refund any money. Aircel is the first operator of India which started providing unlimited internet service. Pls avail this network.
