Tele Performers - Unprofessional and Offensive Telle sales

Really had a bad experience with one of the telesales individuals.

After informing him I will not be interested in the product and to please remove my number from their contact list as I have not given them permission to contact me (POPIA). He kept on speaking. I informed him I was in a meeting (with a client) and cannot talk now - he kept on telling me how I am rude, etc.

I asked if he can provide me with the number of his supervisor her kept on asking for what purpose. I informed him that I would like to report his conduct, but he refused various times.

Extremely unprofessional spam calling and will not recommend them at all.
