Reader's Digest — subscription gifts not received

I have subscribed for rd and paid a years subscription amount of rs.711/_ last july, but neither i have received the gift books that were promised nor do i think that i have been registered as a customer since i am constantly getting messages from rd group about the entry in the sweepstakes asking me to subscribe.
I want to know if i am eligible for an entry in the sweepstakes as you seem to be unaware that i am an existing subscriber.

Please make appropriate note and do the needful.

Thanks and regards
Saraswathi
