Their IT has been completely hopeless with this product, some of the worst I've seen from modern banking. Since opening the account:
- online purchases with the card are getting an authorisation popup which offers (a) an unknown phone number alongside mine - they cannot explain what it is; (b) authorise with app but the messages never arrive
I had this issue! It took quite a bit of digging to find out why (as I literally could not buy a thing online so didn't give up!)... I ended up going into the branch and got it fixed.
What happened was that I had a Barclays product called 'Ping It' YEARS ago (at least 4-5) and they went through a system change around August where, on purpose or not, it sounds like it linked together a lot of personal info from old accounts I assume based on name / DOB / addresses. I didn't recognise the last digits of the phone number when promoted online but when the person in the bank read out the full number, I realised it was my phone number from >4 years ago.
She got it changed with some ID proof / security questions etc. but it was such a faff. And once she changed it, the app authorisation started to work too miraculously. So I'd rack your brains if you've ever had any kind of Barclays product over the last few years, even if you no longer do, as that could be linking your account to a super old number. I'd forgot Ping It was even a thing, I think I used it once...
Agree with others re. general IT/tech issues with the app and website - pretty shambolic in this day and age...
Hope it might help you!
