SeaPoint McDonalds Worse experience ever !

I stood in line at McDonald’s SeaPoint drive through for 45 minutes only to come to the order station and have the person behind the speaker tell me there’s no ice cream. There were other signs to say that there’s no sprite .. how is it that there was no sign at all to say there is no ice cream. I had to continue in the drive through for another 30 minutes as there is no other way out. Empty handed. When will McDonalds fix their ice cream machines !!!! It’s in the heart of December. Summer !!!! I just wasted hours of my live in the queue only to leave with nothing. Absolutely disgusting behaviour.
