As pointed out, how can I do that when I don't know when the cards are going to drop?
Also the customer service guy I ranted at tried putting me through to fraud detection to discuss it, neither he nor me had any answer for over 30 mins so I gave up and decided to wait for the credit idiots to call me back to tell me 'you fail the affordability check for a £1200 credit card even though you've repaid £10k of mortgage in (under) 3 years'.
I simply would have tried telling them that I would at some point have an outgoing payment of either £649 or £1049 to (FE competitor site) and not to block it, but I can't because they won't even answer.
Its the same thing for every single bank.
