*****ing money. Popi act ask where you got our bank account information

Just got a sms that Guardrisk has deducted money and we have no idea for what this is. Where did you get our banking details? . Who signed? Popi act has been activated. I will contact the ombudsman should this not be returned and resolved by tomorrow. We have sent a message on your website to contact us. How can you just do that. Please have the proof of signed documents or actual voice recording ready when you call.
