Trouble with UPS

UPS tried to deliver the DC/DC converter, an AC/DC adatpter, a 3.5" to 2.5" hard disk adapter and an ATX cable to me today. Since I wasn't at home they threatened to deliver the stuff the next day. I phoned, moved the delivery to Friday; they tried again - in vain - on Thursday. Hello?! On Friday I phoned (their office opens at 7:30am) to change the address to my work address. After I gave them the information I'm told "until Monday then". Why Monday? Well, since the address changed... Argh... So, Monday then, while the stuff could be home safely since Wednesday.
