WhatsApp banning for NO reason

Whatsapp is really testing my nurves. They banned me without ANY reason, I just sent my normal messages, and the next thing I know it shows a message that "this number is banned". I have sent a thousand emails and the only response I got was that they have reason to believe that I have violated the terms and conditions. I run my business on whatspp and I am losing so much clients by not being able to access my account. They ban you without anny reason! And then there is NO WAY you can contact them to try and solve the issue
