Need a screenshot for uber $300 referral code


I need help. I started doing UberEats driving in May 2018 with a referral code from a friend. It was $300 for the referrer and $375 difference of earning for me. We both saw this promotion and I finished 50 deliveries. However, uber is refusing to put up the deal on their end. They keep saying there was no referral promotion of $300 or to send them a screenshot. But that promotion is no longer there and now they are lying and saying there was no promotion like that. I swear there was!! That’s what I applied for. Has anyone in Richmond seen that promotion around May 2018? If anyone has a screenshot of it, please share it.
Thank you.
