I’m disappointed that TS Anil won’t be sliding into the DMs of Tescos CEO to have a rant 
More realistically, there are specific channels of communication that you need to go through with businesses - especially the size of Tesco. You can’t cut everyone out by going straight to the top and expect any kind of response.
I doubt Tesco really have anything to do with their payment terminals either. They probably subcontract them to an entirely different business.
Unless you’re a Karen
Hey @Peter_G I just double checked with our team here to be sure I was 100% correct here. We do still calculate interest on pending payments as these are technically still in your balance.
If you’re going to post stupid things, expect people to not agree with you
Even if there’s a CEO to CEO discussion and an email goes to ALL staff and they all read and understand it. What’s going to happen the next time Karen is getting angry in store? The far far easier thing to appease the customer and get rid of them is to lie. That’s not the way you want things but that’s what is going to happen.
Thanks, Kyle. This is what the Customer Advocacy team wrote to me (emphasis mine):
To clarify;
A transaction held in an authorisation hold will not accrue interest as part of your Premium benefits. This is because transactions in an authorisation hold will not be counted as part of your current account balance. This is covered in our Monzo Premium Savings Summary;
“We’ll calculate how much interest you’ve earned at midnight each day, based on the amount of money in your Monzo current account balance and regular pots”
That being said, feedback about making this clearer for customers has been logged with the relevant team.
I’d very much like what you’re saying to be true. But according to Customer Advocacy, it isn’t! If you’re convinced it is, let me know and and I’ll raise it in the app!
Hey Peter! I’m Lauren April and I’m a senior complaint handler from the Customer Advocacy Team.
Thanks for your patience here - we can confirm that our colleague Kyle is correct and we do still calculate interest on pending payments. We’re so sorry for the confusion caused here.
I would love to have a discussion with you about our final response and a full review of what’s happened, so if you could email us with your details to complaints@monzo.com, I’ll take a look out for your message and get back to you asap 
For the third time in a year I’ve been double-charged at Tesco again tonight. The manager advised me that it happens “all the time” and that I shouldn’t worry. Is it Tesco or Monzo where this is failing? We really should not tolerate this - I have never seen it with any other bank or store.
To answer your question, the fault is with Tesco.
And to respond to your second point,
This is because:
This was fixed last July:
I think the fix was relating to situations where the duplicate charge would appear later when it came to the transaction being settled. I haven’t had any further issues with Tesco since that fix.
Not sure if that’s the issue you’ve had today @andrewpclark or whether it was situation where the payment failed at the till (after the authorisation went through) and you then had to redo the transaction causing the temporary double charge.
This should rectify itself within a few days, as mentioned above, not a Monzo issue. It’s happened to me at Boots a few times too, never bothered to find out why but it’s always sorted itself and refunded the second charge.
I’ve had this issue once before where I got double charged with Tesco when using my Monzo card. Was frustrating but managed to get one of the payments refunded soon enough
