Airtel
Without any reason charging rs.20 per week

Sir,

Every week I receive a service message and after that i'm charged rs.20 from my account.

I have not subscriped to any such service.

After i'm charged I receive a message which says that 'Thanks for using (Subsciptions, TextBasedServices) subscription service on Airtel WAP.'

Please see sort this problem out as fast as possible.
