PATHETIC SERVICE!!!!!!!!!!

Ordered something from Amazon 7 days ago. Received a QR code/pin same evening. When I went to the locker next day it said wrong pin and scanner did not work. I sent emails, I phoned them. Eventually my package was there (according to email) and I could collect. When I got there, same story. Phoned the help line, message says they are offline, I can come back again next day (the cheek they have). Does real people exist to talk to??? I only reach robots!!!! Email next day, No response. This is pathetic service!!!!
