ShopCruze — lucky draw contest

Hi team recently recieved some online lucky draw contact and recivied 1 lakh winning prize value in that letter with coupon. Is that fraud or company related thing.

Because look like in additional note asked to pay advance tax amount from our end. Kindly check and confirm.

Is there any lucky draw contest planned from company side for 9th anniversary celebration. This will help me to lot to further move if it's fraud.
