BSNL
Terrible service

I got message from 51819 that Rs. 30 has been charged for dating service renewal which i never subscribed. I called BSNL customer care and every time i got different option to send to unsubscribe the service which i never subscribed. The executives given me following options and none of them is working for me.

UNSUB DATING &-gt; 51819

UNSUBS DAT &-gt; 51819 / 55000

UNSDAT &-gt; 55000

UNSUBDATE &-gt; 51819

UNSUBSCRIBE &-gt; 51819

Also at last they told me if its still not working then go to exchange and make a complaint. As this service is not from BSNL. I am fade up of all this... i am user of BSNL from last 7 years. How can they reply me like this...
