Airtel — without any information talktime money deduction

I am such a very disappoint with airtel service, i am living in out of country but still i keep on my airtel number because of some personal contact and work. And airtel charged my talktime money without inform me, they activate my international roaming, glamourzone service & many more them self i didn't request for any service. That glamourzone service is re-activate every 7 days automatically. I am going to upset for this service.
It's my humble request to airtel or their team please return my deducted talktime money on my mobile number and please deactivate these service like international roaming, glamourzone service and all unusable for me.
