Airtel / Yahoo Zone
Unsubscription not working

Sir,

My Kolkata Airtel mobile number is 9163894371. I want to unsubscribe my yahoo zone service of airtel. But there was not any link to unsubscribe. I sent a sms to 'YUNSUB' to 58243. But that is not working also. And yahoo cutting rupees 10 in every 10 days. Please help me to get out of this subscription. Thank you Sir.

regards,
