asurion insurance services Walmart Product Care Plan They have given me the run-around just to receive my refund for a tablet purchased with the Wal-Mart Care Plan Tennessee

I have a Walmart care plan on my Samsung Galaxy Tab A and I have yet to receive my giftcard via email.  I submitted a claim for my Samsung Galaxy Tab A and was initially informed that I could choose a replacement. When I went online to get a replacement the tablets offered were 1/3 to 1/2 the price I paid for my tablet. I then chose to receive a refund. I called on December 26th and they stated I would get a giftcard. The item was received by the warehouse. I called again as I had not received my giftcard and had to speak with a manager on December 29th. They said a check was going to be cut but the supervisor changed it back to the giftcard. I was told I would receive the giftcard via email within 24-48 hrs. I called again on December 31st and they said I had to wait up to 72 hours. I called today (January 1st) and they advised me that they sent the giftcard via email on the 29th. I checked my spam, deleted folder, and inbox and did not receive it. Now (January 1, 2018) I have to wait up to another 24 hours to receive my giftcard of $149.00. That's if I get the gift card.
