Slickdeals Gift Card Denial

I joined almost two months back and finished all the needed tasks, but I haven't gotten the gift card I was promised. I set up the extension using the promo link back in January 2024 and kept it installed for more than 60 days. After contacting Slickdeals about this problem, they promised to send the gift card once it's processed. But then they said I had several accounts, so I couldn't get the promotion, which is not true. Even after I offered to prove who I am, slickdeals wouldn't budge and said they wouldn't give me the gift card. I'm following up on the $10 gift card that was promised to me earlier.
