Courier guy pathetic service

Unfortunately not the first time, the courier guy in Newcastle has no sence of customer service neither do they care. The first incident was during the Amazon black Friday sale, delivery at work started arguing with the staff while waiting for me to receive the package. Completely unprofessional behavior. Second incident is today I'm waiting for a package from yesterday, first the tried to deliver it to the wrong address even after 3 emails and countless phone calls to change the address. They do not answer the phone and when they do the seemingly are so surprised. I am waiting two days for a package I stipulated I have other things to do I can't wait all day but still have not received my package. Not answering the phone or emails. Customer service non existent.
