Me: Hello Halifax Card Services, my card appears to have been blocked. Why is this?
Halifax: Because you didn't make a payment in November
Me: Oh yes I did
Halifax: Oh no you didn't
Me: Oh yes I did
Halifax: Oh no you didn't
Me: Hello Santander. I set up a payment for Halifax Card Services in November and it didn't happen. Can you tell me what went wrong?
Santander: You didn't set up a payment
Me: Oh yes I did
Santander: Oh no you didn't
Me: Oh yes I did
Santander: Oh no you didn't
