Address:

Thane, Maharashtra, 421311

Hi,
I'm a vodafone user since quite long. Since a year facing multiple issues regarding call drop, network conjetion, cross connection, no network in mumbai circle, billing issues everytime.
Have done complaint to vodafone but gives wave of billing and agains same story in next month. Since past two months, there is huge network issues, hardly incoming and outgoing calls done from this number.
If i am not getting service why should i pay my bill.
Please help in this regards.
