Bad delivery communication.

I've been waiting for them to deliver since last week Tuesday . First day they tried to deliver at my house so I left my ID and proof of res with my mom ,Courier guy told her that they need the holder of the ID .Decided to change the address so they can deliver at my workplace ,next day they still decided to go to my house. When I spoke to one of the consultants she told me that the only place they can deliver at is my house because Telkom doesn't change addresses but if ever I'm not home it's fine as long as my ID is there. Thursday left my ID with my mom only for them to call and tell me they are delivering at my work place while I left my ID at my house. Friday I call again told me my parcel is yeild and told me the only place they are going to deliver at is my house and that will be on Monday. Today I skipped work so that when they deliver the find me home only for them to call and tell me they're at my workplace. Their communication is ****ed up and it's really frustrating.
