Receiving payment

They have errors on their mandate they blame other entity for it when it their fault okay fine I signed a new mandate but now I've been waiting for money after they said it will be sent in 24 hours still nothing and the week has ended and my money was sent on Monday no service from emails or phone calls and I'm yet to receive my money despite Airbnb sending the Money a long time ago and Bidvest themselves telling me it's scheduled and I should receive it soon ?? Sent countless emails no response or understanding
