How to activate de-activated value added services by airtel

Hi, i am a airtel user and i live in uttar pradesh city kanpur. I uses airtel service for cricket to see live cricket scroes every days. But as soon as the ipl ended up i decided to shut this service as it messages some other matches forecast which i don't wish to see.

Finally, i de-activate it but as when i get to know that champions trophy has been started i was thinking that why the hell am i close this service. So whatever no i wan't to know how can i deactivate my service from airtel.

Please help
