Waiting for Godo

I have never been that good at waiting - I always find it irritating but I am having to wait for the Dell person to ring me back - as he said he would.  Well it is nearly two hours after he said he would call back and nothing.   So what do I do?   Call Dell?   Well at this time it is usually very busy so I would be sitting for 20 + minutes listening to some inane musac or wait for the phone call.   I think I am going to have to suck it up and just wait for the call.   This is really starting to annoy me.
