Worst telesales experience

This business must either not train their agents making outbound calls AT ALL, or just hire the absolute worst people who apply for the job. The agent who cold called me today (Clarrence) must be the worst of them all. I answered his phone call, only to have to wait whilst he was in the middle of a conversation with one of his colleagues - shouting in my ear for several seconds. And once I said I'm not interested in any offers, he just hung up as though I bothered HIM. What a disgrace. I'll never use your services if THIS is the kind of people you have promoting your brand.
