Double processing via ubereats (Mimo's)

Dear Mimo's. So yesterday I order via Ubereats for 3:30pm today. I fetch it, and just as I walk out, get an message, "insufficient funds, while processing". Saying that, the uber eats order was double processed. I contacted ubereats, they have a @#$@#$ story about funds being reserved. So I climb into my car, drive to Mimo's centurion, the guy who helped me was speechless. Honestly, why are you as a firm doing business with someone who cant even bill correctly ?

The best part, I will now pay banking fees for the "insufficient funds" error. (because of the double processing).
