Reader's Digest — Demanding excess amount for the products

Address:

Maharashtra

Dear Sir, I am a subscriber of Reader's Digest. Last year they sent me a sweepstake, A catalogue was included. It was said that a customer should select products of certain ammount. I had selected three products and send a cheque of the same price to them. I got the products. But after some months they started sending me the notice of overdue bills. Every thing was priced 499 rs. according to them in the catelogue, but now they are demanding extra money for every product. My account number is[protected]. I sent them mails but they didn't reply. I tried to call them on their office number[protected] and 67122622 but they are not replying! please do the needful for me!
Your's Faithfully,
Santosh Patil
