Deactivated my account with no explanation

I have a recruitment company and I have been placing adverts with Indeed for over 4 years now and suddenly they deactivated my account and said that my business is not suitable for them. When I asked them to reinstate my account and to give me an explanation as to why my account is unsuitable for them now after posting on their site for 4 years they asked me to send them proof of my business and they wanted to know who my clients are. I told them that I would not revile my clients and I emailed them proof of my business. They then rep**** saying that my account has been deactivated and that their decision is final with no further explanation. They are a free site but if you don't sponsor the job they now deactivate your account. They are running ****s as per previous reviews on them, why else would they want to know who my clients are? Do not ever trust Indeed.co.za
