Indecent behaviour

I would like lodge a complaint against one of the employee that works at mutual and federal by the name of avashree harillal. She is being using the company telephone to call my husband to encite and flirt with him. She has also being having phone *** with him. I'm outraged that such a well known company as this hires people of that calibre and they are allowed to used the company property for their own personal advantage. I have tried to address this issue in my own personal capacity but she thinks that she is working in Cape town I'm unable to do anything about it. I hope this matter is taken care of in proper manner as this is very distressing and is causing problems in my marriage
