The River Palace Vaal River does not pay accounts

Business ordered product from me and never paid. Every time we contact her a new excuse. Business owner claims she doesn't pay the accounts but she is responsible as the owner to ensure suppliers are paid. Then she pretends she does not know who she is speaking to on whatsapp even though there is a chat history. Still not paid the account 6 weeks later. Owner claims to own 17 businesses but supplies gmail email.
