Food never arrived!!!! and no refund or explanations????

We placed 2 order via mr delivery, my wife placed one for Burgers from NNK sport bar and i placed an order for desert from Rocco Mama's, The desert arrived, but we have not received our food and have not even gotten a call or a message to state what is going on? we cannot get a hold of support as the phone lines are closed for lockdown, and they are not even responding to the emails???? this is the worst service ever from Mr delivery. very dissapointed!!!!
