You can't check it, the only way is to talk to cc, or you will come to know after you get your bill. The cc is so pathetic that they themselves doesn't know how to unsubscribe and the keep on making excuses like could you call after 1/2 hr as the server is down, i am unable to check bla bla bla. For some items you have to send message like UNSUBCT to 51234 for callertunes unsubcribe, UNSUB EDUCATION to 53030 for educational pack unsubscribe. For rest of the items you have to ring 51234863 and follow the guidelines. The day we get number portability,I am sure half of the reliance users will opt for other subscribers.
