Airtel — without intimation extra bill amount

Address:	110005
Website:	airtel.in

Hello,
This is mandeep singh from delhi and i've been using this no. From last 1-2 years ([protected]),
My postpaid bill plan is rs 649/- every month and been to abroad on 21st december to 28th december and airtel has applied extra charges on my bill which is of 3200/- something in december and 1200/- on november bill also.
Without giving any information to me about the charges, the customer care is telling me not to consult airtel store instead of customer care, i wanna ask a simple question why you have given a authority to airtel store to help consumers, you should stop the license to open airtel store then if they dont know anything and moreover the executive working in airtel store is giving false information to me nor you guys told me that i will be charge 649/- per day as a international charge.
Now they are giving me the information about the dubai standard rates charges but my question is why you guys not gave me any information about the plan and the charges and also i have talked to the customer care executive the have given me the interaction id (26
[protected] and before going to dubai, i went to store to know about the international plans and they gave me false information to me there also by activating international umbrella pack and told me that you now make calls to anyone from there and i had activated the rs200 pack for my no. Also from igi airport also
Please help me guys
