Bad Customer Service at Steers Cavendish

I ordered 2 Coke Zero's and a milkshake via Uber Eats. The coke zero's came in paper cups, flat and not tasting like a coke zero. I called the store and spoke to Samantha the manager who kept on telling me that it was coke zero that was sent. I asked her to come and taste it as she was practically calling me a ****, she even wanted to call the person that made it to come and explain. Not a single time she she offer an apology, she was just repeating the same thing that it was coke zero over and over, enjoying the fact that she was making me angry. She dropped the call after I told her that I will log this on Hello Peter. Customer service sucks and no people s****s at all
