Where did you get my information??

At 15h39 I was phoned from Discovery life cover. Upon answering my phone the consultant greeted me by name. I raised my concern regarding the consultant having 1) my number and 2) knowing my name. I wonder what other information you have solicited of mine? I asked the consultant where she got my information from, and she firstly mentioned Telegistics. I asked her to spell it for me and she refused. I asked to speak to a manager and my request was refused again. The line then went silent and after a while the consultant spelled the company name Telegenics. I asked for her name and the consultant proceeded to abruptly end the call. I would like to be contacted on ********** 692 to get factual information as to where Discovery got my information from and furthermore I would like to know which consultant I had spoken to (I was called on the same number as stated above). Your urgent feedback will be appreciated.
