Paid for express delivery from Russian embassy my misfortune they chose to use DX. sent for delivery Friday 19 november 2021. recieved a text saying unable to deliver on monday 22 november 2021. no reason given. went on to say delivery would be the next day Tuesday 23 november. No delivery was attempted and no further contact from DX As of 24 november still waiting for delivery. There is no way to contact Dx for an explanation. The automated phone line offered to deliver on 25 november 2021 having no other choice had to accept- this means waiting for delivery 4 days -if it arrives.
