Waitrose Taking Payment Twice

[NellieJean]

Had our weekly Waitrose delivery this morning. An hour later I happened to be looking at our online banking and they have taken the payment twice. Called Customer Services only to be told it’s a glitch which they have known about for two weeks and only one payment will go through.
Given we are all told to be aware of scams shouldn’t they put a warning on the website or email customers about this.

Did they refund the second payment?

I expect one of them will be pending and will drop off when the actual payment registers. It's commonplace.

This. I’ve had it a few times with different transactions, weirdly Asda does it more often than any other supermarket.
