Bharat Sanchar Nigam [BSNL] — Sharp practice by bsnl to trap consumer in agreeing to pay for products

I got a new sim card from bsnl. As soon as put the card in operation, bsnl a flood of "buzz" started flowing for services at some cost. Why do i call it sharp practce?
A) the message appeared on the screen in english - which many cannot understand
B) for "ok" it asked to press the button which is normally used to see options, i. E. If one reacted by pressing the key which is the default key for options bsnl takes it as ok for the payment
C) by not giving the route for ok via an intermediate step of options, bsnl sets a trap for the new users. As a fair practice the route for an agreement to pay be at least a two step process via options etc.
Thanks
