VERY BAD COMMUNICATIONS

I have just phoned Nedbank Group Insurance 7 times & they DONT LISTEN. I called yesterday to *** & spoke with Riana who very kindly gave me an email address to send communication to. I seem to have the email address wrong & phoned 7 times this morning. I got put through to Call centre, very cheeky switchboard operator who repeated himself & wouldn't listen to me. What is wrong with people not listening & as a switchboard operator patience should be a virtue. I want the PROCUREMENT DEPARTMENT OR THE CORRECT EMAIL ADDRESS FOR THEM.
