Shocking Telesales and coplaint follow up

Shocking telesales consultant and complaint follow up: 1) I was called on my mobile interupting an important business meeting, first off without permission to do so..secondly asking for my wife..question where did they get my mobile no. from.. 2) Then the salesman 'name on record', continued to pitch to me a free courier package..to which I asked what are you selling..with a vague answer managed to establish, they are promoting a pad of some sort, thereafter I said I'm not interested.

3) The salesman continued rudely..and at a point I requested the name of a supervisor..to which his response was: I was a third party, not my wife. I managed to squeek out his name.

4) Called in to their office to get a supervisor on the line, A supervisors name was given to me, but was on a call..left message..called again later..in a meeting.. Called again later..receptionest demanded my ID no in order to log the call to which I refused not being a client of theirs. and refuse to give my personal information for obvious reasons, apart from name and no...and transferring me to the specific supervisor and said would refer to another supervisor.
