Promo Visa Prepaid Card

I received my Claim Validation email on June 27 but I have not yet received the $100 Promo Visa card that I was eligible to receive. I reached out to the Dell Promotional Support Team and was told that I would receive my card by August 2. I didn't receive it and again contacted the Promo Team a week ago and was told that they would investigate and provide me with an update. I didn't hear back from them and sent another email 2 days ago to which I have had no response. I am by now very frustrated that I have not received the promised Promo card and that I am not getting any answers.
