Uber Eats & KFC Hatfield passing the buck to one onother.... Me? I just walk away.

I ordered ORIGINAL Coke with my meal, which costs more than the Coke ZERO, but the Uber Eats guy brought Coke ZERO. He said he can't return it and I have to sort it out with KFC as they gave it to him like that. Typical passing the buck to one onother. I'm not interested in a refund, but also I won't order from Uber Eats nor KFC Hatfield again. Bye Felicia.
