Idiots

I get a call from these call centre people every day, asking to speak to one of the employees at the company I work for. I have explained numerous times that calling a sales rep at the office is a pointless task as he is out on the road, I then suggested they call on his cell and if he does not answer they should try again later. African Bank telesales have now decided to harass me every single day by calling me first from an anonymous number they then say nothing and when I hang up they call from 010 252 000 and do the same thing. This is pathetic
