FNB can't take a message

I started at a new company last year October and got a company phone. In this time, FNB has called me more than 20 times to talk to the previous owner of this number. <br> <br> What do they expect after the first time I did not know how to get hold of the previous owner? I have started to get nasty to innocent call center operators due to a flawed system.<br> <br> Please leave me in peace, especially on a long weekend!!!!<br> <br> I have never been an FNB client, and now I know why.
