I received my new card and it has changed from visa to mastercard, however | went to pay for something online and my bank has blocked it. I have ordered about 3 times before under visa - so is the mastercard making a difference.
Somewhere along the line bank is thinking it is an international payment but it is UK.
bookbinder - I can't hear well on the phone. There used to be on Santander - send secure message and that was great but they have taken it off and you have to use that stupid Bot thing - absolutely hopeless.
