Worst call centre agents

I was just contacted by a call centre agent at 15.06 from number ***, as always, the agent was incredibly rude after I told her I was not interested precisely because this is the rudest agents and most annoying company I ever had the misfortune dealing with. I honestly don't know how they stay in business. I am no longer a customer of their's, nor will I ever be seduced by their obsessive marketing tactics. It's plain harassment!!!
