Dear Sir,
I have Rs.102.00 balance in my number 9556858177 i.e. Odisha circle Airtel number on last week i have recharged.But airtel making fraud now i have Rs.2.74 in my main balance.When i called to airtel customer care servoce about my money deduction the customer care senior executive told me that i had activated a wap service on internet i.e. Top online doctor service on april 2015 and when my balance will more than 50 rupees on july month 2 times they have deducted Rs.49 i.e. on 24 july 2015 & 31 july 2015 Now my main balance is Rs.2.74 also i have never activated any services.They are making fraud.This is totally disgusting. I can’t tolerated any more.I want my Rs.100 rupees back.Please consider my issue.So many times i have facing this same.Previously also they have activated service from there side & when i had complained only they have stopped the service but my money was deducted. This is cheating. I want justice by refund of my money otherwise i will go further to take severe action on this brand.We are recharging money with our earned money & these peoples are deducting it on their choice. This is totally not fair.I want quick action from you.
