- BBBridgette Barnett2 days ago1.0I ordered a huge order for over 100$. They delivered to the wrong addressat 1215pm I even wrote the address and second time in directions and said to give to secretary inside the school. They left it outside a door on the ground. It was over 80 degrees and the drinks were ruined. I tried to get someone on the phone to correct it immediately. I was still calling on and off at 7pm. I want my money back but I cannot get any person on the phone!!!!! Horrible. I'm going to let a lawyer talk with them if I don't hear from them tomorrow. This is ridiculous. Horrible service!!!
- DMDesmond MontoyaJan 12, 20265.0Mmmmmmm...
- MGMartin GarciaOct 19, 20251.0I’m trying to reach them for a single drink, I have called 10 times on a Sunday during the football games with no answer. Also please not the website charges 3% to order a drink online. So staff doesn’t care about customers and company wants to drain its consumers of their money as fast as possible. Buy a juicer at home!

- RTRachel ThomasSep 7, 20251.0They took like 20 minutes to make one medium drink. And the bathrooms smelled disgusting.
