Bigby put redbull in my mocktail when I asked them not to

Last week I ended up at the doctors for pelvic pain and pressure and I was having intense Braxton contractions. That morning I ordered a bery blast mocktail without redbull and a little zip. (Zip is a natural form of energy - 100mg caffeine.) I had asked for extra flavoring too. It tasted a little different and I didn’t think too much of it. But ended up at the doctors that day. I ordered it again at another bigby and stressed that I’m pregnant and cannot have redbull whatsoever. It taste so much different and now I realize that they put redbull in my previous one. Should I contact them? Or leave it be.
