Airtel — unnecessary deduction of my prepaid mobile balance

I recharged my airtel number [protected] on 10/06/18 at 11.56 worth rs. 100/-.
Within 15min the whole amt was deducted due to some some value added services for which i din't applied.
I called on 198 complain number bt they said that currently system is not working so it ll b returned till 13/06/18. Now m trying to contact back bt unable to contact and my balance is not returned yet.
M fed up with this compny & its poor services. From last 10years m my whole family is using airtel bt currently we r facing problm with this company&its poor services. If my problm is notv solved within time i ll switch for other company through portablity.
