[Resolved]  Vodafone — illegal roaming charges

I am using vodafone postpaid mobile connection. And my number is [protected]. I was said that there are no roaming charges for Maharashtra and Goa. But still they charged me roaming charges in maharashtra. I enquired it and they said me they charge roaming outside mumbai and if i don't want this to be charged i have to activate happy to roam. As per vodafone instructions i paid my bill and went to kharghar vodafone gallery to activate happy to roam. I gave my request to Mr. Pradeep to activate my happy to roam. Further i didn't knew whether he activated or not. But in next month again i had roaming charges in my bill. Again I called customer care and they replied me my happy to roam was deactivated by some of their employee and they will investigate it. But not for any of my mistake i had to pay roaming charges again. Now this is last time and now on if i see roaming charges in my bill I will directly switch to some other network. But i don't get this why they charge us roaming charges even if we are in kalyan or panvel.
