Vodafone India — harassment over billing and plan changes

Address:	Mumbai City, Maharashtra, 160022
Website:	www.vodafone.in

While selling i categorically asked and was assured i will be on the plan including discount of ₹200 making my effective rental of ₹299/- will remain unless & until i change my plan. However, a couple of months back they without taking my consent or intimation changed my plan to ₹599/499/-. On contacting them i was literally scolded by their executive on toll-free who didn't even let me complete my problem? I on a paid call was being scolded like anything and even on my saying don't release the call mr. Lekhraj dropped the call & his supervisor denied taking the call. I am now being charged out of the window including international roaming charge every month. Please help me in it as i have no hope that vodafone will. On every contact there is a different info with someone saying my plan has not changed, someone says yes we have upgraded benefits so the charge, yesterday one said on chat nothing has changed. My plan is the same including the discount which as per her is still being given.
