Whatsaap banned my business account for no reason.

Hey there, Whatsaap systems have mistakenly banned my WhatsApp business account. I was only contacting people who had filled in a Facebook form and had asked me to contact them. The form was provided by an ad. How do i get my account unblocked as I was not spam messaging anyone. I was only contacting people who had asked me to contact them. 
I can provide proof that not even a single number that I had contacted was spam. They all asked me to contact them
