Vodafone India — Befooling people

I recharged my number yesterday by 255 where i should have got 2gb 3g data . I got 1gb instantly but the next was supposed to be credited in next four hours. I didnt get it. I called customer service six times, they heard my query and either kept my call on constant hold or disconnected the call. I want immediate action and want my 1gb data back. My number is [protected]
