Untrust worthy service

I ordered a meal at this Mochachos over the phone and was going to pick it up later,45 minutes later when i arrived for my order the stuff hadn't placed my order or they give it to someone else only god knows.This is so unprofessional,if you can't maintain the calling service than s**** it,i can't have the cashier asking me if i'm in a rush,i would have came myself if i wasn't.
