Order 3 smoothies and received 3 juicees. Not sure what they were blending but it's noway they put ice in it. All 3 were literally just juice. Kids were disappointed. I had 3 so I didn't realize it until we were already back on the road or I would have returned them for smoothies. Given how much they raised the prices they need to train their workers to give a decent product.

On June 28th 2025, I went to Jamba Juice in Sierra lakes pkwy. Angelica N was the only worker this day around 12 noon and she was very rude whiles I was ordering. I ordered a smoothie and an oatmeal bowl. The smoothie wasn’t good and as for the oatmeal is very disgusting. The oats weren’t cooked well and I ended up throwing it away. I was really disappointed on the service and the food on this day. She seemed very disorganized and was rushing orders. She mixed about 4 peoples orders up. She didn’t look happy to be there. Overall I wasn’t happy with the food or service and the attitude Angelina N showed towards me.

I ordered a white gummy smoothie tonight and I specifically told the guy working behind the register I wanted it thick and not blended all the way through so that there is fruit chunks in the smoothie still. I tried the smoothie and it was completely smooth and had not 1 chunk in it. I went back inside the store to ask for it to be remade as I did not receive what I had asked for. There was a girl working there also who I had asked for it to be remade and she at first gave attitude for me even asking a question. She remade it and it STILL did not come out right. It was completely smooth again. Mind you, she handed me the remade smoothie and said “this one should be better for you, have a good night” while walking away completely full of attitude. I just simply asked of you to make the smoothie I paid for and had to repeat myself on how I wanted it made. And you still want to give me attitude? I will not be going to this location ever again and I highly suggest she gets trained on how to treat customers.

My order got sent to this location on accident by an app glitch. Tried calling the store to call about the order and no one picks up the phone. I’m can’t drive an hour out to go in person and get refunded. Very frustrating.

Understaffed. One girl working felt bad for her. Waited 30 min waiting to take my order and ended up leaving. Seems like the prioritize the online orders.

The location off Sierra Lakes in Fontana is the best one to visit.

Store had a sign that stated on a break will be back in 45 mins and the doors were locked. But what about the online orders that were placed?
