SVB Ventures review for Facebook & Instagram

Not sure why most of the time Ads accounts are getting banned or restricted. We are clothes and accessory seller for women, men and kids still our ads account got restircted or banned and we are not getting any solution.Removal of restriction is very difficult and no proper support from FB. There is no Live chat support from FB who can help customer to clear such restriction or banns. thanks FB to provide live chart support since we are not expert in FB..............THANKS
