GiftRocket  - gift card for shaking crab not received

Gift card not received. I was given a gift card email for $50.00, to be used at the Shaking Crab. I downloaded the information and was given a confirmation number (#DQ7KXGBZVCYT). I have not received the gift card yet. It has been almost month (3/21/2019) since I've downloaded the information and I would like your help in resolving this issue. I have tried calling you in regards to this and all I've received is an answer that has led me here. My email address is: [protected]@msn.com. I am looking forward to hearing from you.
