In our block in Ajijic Amazon has made 3 deliveries in the last 7 days and not once did the driver have a face mask on when arriving at the door to deliver a package. Two days ago I stopped him on the street in front of my neighbors house to ask why no mask, he told me he has just finished lunch in his truck and forgot to put it on. Yesterday he made a delivery at my house and a worker received the package, same man, no mask. Unfortunately I was not there to snap his photo .. Does anyone have contact info for Amazon.. in the US I had a contact phone number that was invaluable in getting action on any problem with Amazon .. here I can't even find an email address, let alone a phone number..
