Account banned for no reason.

Yesterday I was just browsing youtube when i get a notification saying this account is not allowed to use whatsapp anymore so i go ahead and request a review because why has my account been banned in the first place if i never broke any rules or went against the policy. They then said that they reveiwed my account and that its activity goes against our terms of service. But keep in mind i havent done anything wrong. Now im blocked from my whatsapp account and i cant message my friends or family. ridiculous
