Uber Eats BS!

I ordered 2 x nuggets with free Mc flurries. The idiot driver delivered the nuggets without Mc flurries, he then left to fetch the Mc flurries however he returned with only one Mc flurry!!! He asked me to wait for him he will correct it and return very soon, I've been waiting for 3 hours. I've contacted Mc Donald's and they advised that they are waiting for him. He hasn't returned. Uber Eats is the worst service in the history of time!
