Missing part of transaction

Here's an email I sent coinbase a few weeks.

Can anyone shed some light?

(Hi,

I had a friend transfer €50 to my coinbase BTC wallet, minus his fees this came to 0.00333416 BTC or €46.72.

When it was received in my wallet it was only 0.00115 BTC or €15.59.

I failed to see how over €31 can be taken in a transaction fee for receiving BTC.)

Their reply is long and doesn't really answer it as we didn't use email addresses just coinbase addresses

(Hello and thanks for contacting us.

Here is some information on Coinbase fees:

We do not charge a fee to receive and store digital currency, or accept merchant payments.

Any transactions sent between Coinbase customers by email address take place off-chain (not on the blockchain) at no cost. Coinbase does not pay the network mining fee on behalf of customers for outgoing digital currency transactions.

When buying or selling digital currency on Coinbase with a bank account or fiat wallet, the conversion fee will be displayed prior to confirming your order and will vary based on your location, payment method, and other criteria.

For more information about fees, please refer to this page: https://support.coinbase.com/customer/en/portal/articles/2109597

If this did not resolve your issue, please respond to this email and one of our agents will get back to you as soon as possible.

Thank you for using Coinbase!)

I went back a week ago with this and have had no reply since., has anyone experiencedthis?

(Hi,

Thanks for your reply.

It still doesn't explain why after he paid his fees,0.00218416 BTC (€31.13) didnt come through with the payment?

I was with him when he made the transaction so what could have happened?

I'm quite confused by it because all other transactions have come through at the correct amount, are you able to clarify for me please?

Thanks again)
