Sorry for the random message.could you help me with this. My friend is having problems with the Casumo source of wealth. They are now asking for proof and written letters from her sons who paid money into her account for rent. Proof of where the money withdrawn from Paypal came from. She has a pending withdrawal of £800 and they take about 4 days to reply to an email and it’s all getting annoying. Can they ask for this much information, especially when some is person to her sons?
