Change to credit card security system for online purchases
Now one has to put in a security code as part of the payment process and that code is sent to one's mobile number - but that's not the number that they have registered on my account. I didn't have a mobile 'phone when I obtained this card (yes, it's that old), so the only telephone number registered on the account is my landline. They think it's a mobile number but of course it isn't, so I can't be sent a security code at all.
One cannot change one's registered mobile number online; only by telephone and - as they don't bother to put on the notice about that problem - only during their limited banking hours. So the customer goes through the entire credit card identification process, only to be told to call back tomorrow when the bank re-opens.
And of course one can't hold onto a delivery slot overnight without being able to pay for the groceries....
All that trouble could so easily have been saved by notifying customers in advance of introducing this complication, giving us time to ensure that we had registered a current mobile number on our credit card accounts.
