Husband accepting the khula

Q: I got married in the year 2006 and have two children. My husband got involved with some lady so my husband neglected me a lot. I got pregnant but he didn't care. He gave me a lot of tension so I had a miscarage. When I came to know about his affair I got hurt and started fighting with him but I accepted his new love with that lady but I told him that you stay happy and keep her away from my children but he kept on beating me and abusing me so that I may leave the home. I left home more than a year ago and within this separation time period he didn't keep any relationship with me nor did he divorce me. He didn't give any maintaince for the kids. He used to send 5000 in my Account for kids but 5000 is not enough for kids education and other expense so I took khula from him in September but he refused to give divorce as he has sold my 3 gold sets and he has not paid my huq maher so these are the reasons he didn't divorced me nor he accepted me as a wife but on khula he agreed. Now tell me is my khula done or not and what is my idaat time?

Exposing the injustices of a company

Q: I worked for a debt collection agency in Qatar which dealt with defaulted Vodafone Qatar customers, my job was to collect money by calling them, my management was forcing me and everyone in the agency to abuse, threat and blackmail customers. I refused to do that hence the agency is terminating my contract and sending me back to my country, I have recorded some of these abuses made on my phone and if I send this to Vodafone UK, the company will lose their business, eventually close and lot of people will lose their jobs. Would it be right Islamically for me to do this as they are involved in illegal work or do I have to just forgive them and move on? Please shed some light this matter please.
