Vodafone India — activation of services

Address:

Mumbai City, Maharashtra, 400706

I have tried to reach correct people to talk but not getting any response but a general answer. I had asked for an international roaming pack activation on 29dec18 before my thailand trip to which the vodafone customer care executive only activatd a basic international roaming pack of 150 rs. Due to this i have incurred a bill of rs 4963/- out of which approx 3600/- are data charges. Why am i being paid for a mistake from your end? Why the request was not taken which was asked for?? Can somebody pls wake up on this and arrive at an amicable solution as am fed up chasing people without any luck. Please do not give standard replies which i am getting. I am being penalised for no fault of mine and an absolute lack of services your end which you are failing to accept!! Awaiting some positive anser from your side. I will use every available mediuim to get in touch with you and try my best!
