UNHAPPY LOYAL CLIENT

I have raised concerns multiple times about the delays in customer service! Twice now, I've received promo codes — including the EAT20 code sent today. When I tried to use it for a breakfast and gin tasting, it shows as invalid. I contact Hyperli, and their turnaround time is 48 hours. Please explain how this benefits any customer when the deal is only valid for one day? Hyperli, it's time to step up your game! You're losing loyal clients!
