ADT sales call

<p>I recieved a call from a number I didn't recognise (+27 10 ********** ), I answered and a lady introduced herself as Sweetness from ADT, I then asked what the call was regarding and she said an alarm system, I then said I don't have an ADT alarm system and asked politely if it was a sales call, she said she didn't know what a sales call was, I then asked if she was calling to sell me an alarm system, she then said she was calling to talk to me, I then asked politely what she had called to talk to me about and she made a clicking sound and hung up the phone. These cold calls are highly annoying as standard but even more so when the person calling is blatantly rude and poorly trained.</p>
