Threat received from Cell C call center agent

<p>I received a call from Cell C on ********** . The agent told me it is time to upgrade my contract. This made me angry, since I already upgraded - he confirmed that the upgrade was cancelled (which I did not do nor approve). Full disclosure - I was rude to the agent due to being very angry. We went through the entire upgrade procedure again. Once done I thought that was that. Thn my phone rang again from the same number. I answered and the same agent asked me to confirm y home address. Once done he told me that he just looked up my house on the internet and that it is nice and there are nice trees there. Then he said goodbye and hung up the phone.</p> <p> </p> <p>Is it Cell C's policy to phone customers and threaten them like this? So, if something happens to me or my property in the next few days is Cell C culpible? Should I rather cancel my Cell C contract and move to a different provider? Or will Cell C send leg breakers to my house if I attempt this?</p>
