Using curve card at 'pay at pump'

Hi can anyone shed any light on the issue I have I filled up £17 worth of deisel and Costco using my curve card (pay at pump) but it has a pending purchase amount on my curve acc and my bank account of £99 any one I can contact about this or can anyone shed some light manky thanks Ian

It’s a pre authorisation. It’s just like the £1 charge you get with most services, I read somewhere on the Monzo forum this is a Mastercard thing. It should disappear when you get charged what you filled up with.

Hey @ianmaxine :wave:
Just as @CJ0206 mentioned, the transaction has been preauthorised a higher amount because some petrol pumps automatically charge you the full amount that you can buy then the cost is adjusted later for the amount you actually used.
It’s similar to a hotel deposit, where you put down a larger amount to cover any costs you might incur, and then you are refunded after you leave the hotel. You should see the amount adjusted in the next few days!

When using an automatic fuel pump with Curve, a large amount is pre-authorized on the underlying card. In Sweden this is 1500 SEK, approx 120 GBP, more than twice the cost of a full tank in my case. Anyway, with any other card I’ve used the pre-authorized funds are released and the real amount settled within minutes of leaving the station, so this is usually a non-issue. With Curve however, it can and usually will take 5 working days before the funds are released, a huge inconvenience if you don’t have enough credit left for your daily spending. For a fintech bank that prides itself for it’s real-times features, I think this is a huge oversight. Please fix this!
