I hate sales people that talk through YOU

Is it me or do you find over enthusiastic people on the phone totally annoying?

They are enthusiastic to the point of being rude, never slowing to listen to any questions and God forbid if you have any rejections...

I took up an offer of a service today but the guy at the other end just refused to slow down so I found it hard to keep up. It almost lost him the sale as it was quite obvious I was just a number to him...

So what do you do with annoying phone folk?
