Call centre being sarcastic

<p>Was just cold-called by Vodacom agent. Asked what it is regards to and they said about my account and high fees and automatically assumed it is to sell something and then said that I am not interested in a new product. He then said: "then why do you use Vodacom" and hung up on me. Vodacom, let that be a reason why people are leaving your network - your terrible cold-calling agents being sarcastic and rhetoric. Guy phoned from ********** </p>
