It's been edited. Did this solve your problem?

I have no clue what you wanted changed, and you have no clue what I changed. Nice. :]

You have two tests that have the expected result as: "Values should not be equal: 'VISA'", but the kata expects VISA. You should change those tests to "Values should not be equal: 'Visa'" or delete them.
Did this kata in javascript.

Phone numbers may or may not have a leading zero, contain formatting for country or area codes and additional information such as extension numbers etc.

031 753 776
039324892
+850 (0195) 1 823 167
+850 (079) 907 489 (ext. 2582)

Whereas a credit card number can be a string or when stripped of whitespace an integer.

4012888888881881
348282246310005
6012 9999 9999 9999
5305 1051 0510 5106

This is also one little hurdle to throw into the kata to make it a touch more difficult/require some thought.

Similar to phone number, credit card number is a string.
