Airtel — irrelevant deduction from my airtel account

Hi,
Amount of rs 99 got deducted from my prepaid number "international roaming rental charges" without any reason on 2 nov 2017.
Number :[protected]. Please refund me my amount.
Also my data pack expired before 28 days. I had recahrged it on 25 oct and now today on 22 nov i am not able to use my data or call. I had recharged for 349 (Monthly with 1.5 gb per day and unlimited calls) i may have to port my number if these things continue to happen.
It is really very frustrating to keep a check on thse things

Thanks
