BSNL - Deactivate BT-OVRSEA (+55888015) Chat Messanger

Hi,

A chat messenger Service that I never used is deducting 15 Rs at regular interval from my BSNL no 9481546535.
I am getting SMS from chat Messenger service 'BT-OVRSEA and +55888015.

It would be of great help if you unsubscribe this service.

Thanks in advance!
Ramesh
