Let me explain the current situation that I’m facing since last night:
I received a transaction notification for around 360 Euros last night even though my balance was 0 EUR. This caused my Revolut balance to be -360 Euros . That same transaction was made in April 2016 but the card hold was released by the merchant as my order was cancelled. I asked CS on live chat why that transaction was back and why my balance was -360 Euros, I was told that their payment processor discovered this transaction and rectified it!! That hold was released by the merchant yet Revolut’s payment processor thinks that that it went through in April 2016!
This is creating a big nightmare for me as the whole issue occured right on my travel date, and will therefore make me more cautions in using Revolut.
I sent all the screenshots to @AndreasK and hopefully He will help solve this problem as live chat was not very helpful.
