Awful Customer Experience

I am really disappointed at the level of disrespect and poor service from your Gateway KZN branch. I ordered a wrap and a drink via uber eats and was met by a very disrespectful manager by the name of Thokozani or TK. Who didn't care to assist me as a customer and a hungry one at that. He told me he didn't know what to do since they false advertised having the sparkling drink when in actual fact they dont and he made it seem like it was my fault. He didn't care for that I was frustrated and demanded I cancelled my order even after I had told him several times times that they had to cancel it on their side since they already started preparing. He was rude and spoke in a harsh tone and didn't care how I felt. Is this how customers are treated in your store? I have bought from your stores all over SA but this was the worst experience I have ever received and I never want to buy from you guys again. The poor service from TK (Thokozani) and his team is baffling!!
