Reader's Digest — Not received gift

I subscribed for Readers digest for one year. After it got expired I received a letter to renew it by cheque and I will get 3 free gifts. So I posted the cheque in the business envelope provided. After 1 month I received a gift through the postman. I thought it is the gift that I was supposed to get, but the postman told that I had to pay 399Rs. I did a mistake by paying the money. but when I opened the wrapper it ws one book whcih was not part of the 3 gifts as mentioned earlier in the letter.
I called the customer care and told the issue. She told that they will look into it. but no reply. Later I wrote several emails.
I also stopped the cheque as after one month of sending it was not cleared. But in the mails they replied that they will send in the next 10-15days. But now more than 3months over and no gifts also.

Since I stopped the payment of cheque, I got a letter that the subscription will stop immediately even though I had paid the money through the postman earlier. The customer care person tells that they have not received the money.
I just dont know what they are upto.

On top of that they send letters that I can win 15000000Rs by sending some form. Looks like some major scam!
