Transferwise

Hi. I transferred on the 6th April and topped up straight away, but I’ve not had an email from transferwise to pay my 50.00 referral fee. I joined using someone’s link. It says normally 1 to 3 days after top up

yeh my brother got the same email as I refered him as a friend. He had to follow the link that takes you to transferwise and register with adding his bank details. Then emailed Bulb to say its all set up to receive payment?
