It should be relatively easy to find out for you. There are two kinds of accounts Revolut offers right now. If there is a reference code involved, third party transfers are not possible. Which account informations did you give the company?
From your first post, I assume you used the “personal” account details without a reference code.
I would try to get some sort of proof for the transaction made by the third party. Revolut probably needs further details like account numbers to find a transaction.
From the FAQs:
How long will my top up via bank transfer take to reach my Revolut account?
This varies from bank-to-bank and by country.
From a UK account this usually takes 4hrs, and can take up to 1 working day. BACS payments take 3 working days.
International transfers (from Poland, Switzerland and elsewhere) usually take 1-3 working days.
Transfers from Greece typically take up to 4 working days.
If you are topping up your account with EUR/USD, please ensure you use your 8-digit customer reference number as the reference/description for your transfer, or we will have to manually allocate your top up. This will delay the top-up reaching you account.
