AB Inbev SAB Tzaneen depot out of stock since August and no communication

Zero customer service from AB Inbev (SAB). They have been out of stock since August 2020 on all key brands Black label 750, Castle lager 750, Castle light 660, milk stout 750. Tzaneen depot limpopo. Not even a decence to inform us as small business when we can expect delivery. Week inn week out no delivery. I guess is because of their monopoly. I must pay my employees while no sales since we out of stock.
