Rawleaf - All on a sudden FB disabled our account

All on a sudden we found the account has been disabled without citing any reason. FB never cites any reasons for blocking or disabling any account but As per our assumption the account has been disabled because of certain claims about our Diabetic product. The funniest hypocritical attitude of FB that the same product they are promoting or boosting when we are paying them . Because of account disablement our money has been blocked and it has become their unethical practices to block or disable any acount without citing any reasons. We respect others privacy and security but at the same time if we unknowingly violate FB policy then they should allow us for rectification . If they found as repeater offender then they have the every right to do so. Moreover, as an organisation it is their moral responsibility to return theirs unused money when they are not rendering any services. FB's arbitrator attitude need to changed
