Vodafone — Regarding add on packs

Address:	New Delhi, Delhi, 11009
Website:	Vodafone.in

I'm using Vodafone mobile number [protected] since last five years. Last two months I'm facing problems with the company. Whenever I use Internet, some add on Packs are getting activated without request and a huge amount of balance is deducted. I have complained various times regarding this problem but I didn't get any satisfactory solution. The customer care executives didn't take it seriously.I'm harassed. Kindly take appropriate action and solve the problem as the earliest.
