No Communication Skills!!!

This is unacceptable! My parcel had to be delivered 2 days ago, as that I was working night shift I obviously slept when they called me, unable to answer directly I tried to phone back but it kept saying that the number does not exist? Emailed them someone answered me and we sorted everything out... Last night I received a call stating that I will receive my parcel on Monday .. when I emailed again and asked if it's going to be tomorrow or Monday I received an email saying I need to verify everything from the top ... When you call them you get placed on hold !!!! Like I don't have time to wait 5 hours before someone can answer me ?? I need to make arrangements for someone to be home to collect my parcel on my behalf as that I'm working shifts.. I can't deal with this really
