Hello @Steveb1471,
First of all I’m really sorry to hear that your ATM withdrawal was unsuccessful. I can see that you’re talking to us on the in app chat to get this fully explained to you.
This is a process that the industry is following. If the ATM reconciles its data that it was indeed unsuccessful, then it will automatically reverse the hold on your money in around 7 days time.
The 45 days is indeed an upper limit that we need to allow for Mastercard to investigate, and this can be resolved much sooner.
