Hi David,
I took out a "Halifax" mortgage three years ago at their Benalmadena office. They did say at the time I could have a credit card, but they were not insistant
on me having one. They also did the Home contents insurance and again no life policy was requested or insisted upon. My own Bank, Solbank only issue
credit cards if you ask for one, which I did, and they are useful for the times you visit. So unless things have changed in three years, don't be bullied into something
you don't want or need.
Best wises for the future,
Paul Smith
