When will my boxes be delivered?

I am still awaiting delivery of my 2 boxes. They got to Pta office on 18 Dec. I phoned on friday and was told maybe saturday or monday 21 Dec. Phoned just after 8am this morning, and was told someone from deliveries will call back. I phone again this afternoon and Dan said he would call the driver. Dan phoned back, and said ud he couldn't get hold of of the driver as his phone was off. So I assumed it was out for delivery. It is now 8:53pm and nothing has been delivered yet. What is going on?
