I think this kata is really tough since the conditions for extractions totally depend on re module, on the contrary, this can be done in many different ways if re is not used. However, I believe the intention is to use the re to the fullest. This kata took me lot of time to figure out, but I feel like I learned some interesting things about re module.

No need to say sorry ;)

Take a good look near the edges of the quotes.
spaces at the beginning or end of the phone number string should result in a mismatch.

48 tests passed and 1 failed. Below is the one that is failing and I am not sure why? Please explain. I believe below is expected to match or is there anything specific that is valid for "+??" at the beginning? Thanks for your help.

Matching test for ' +21 45 567890'
Test Passed
Matching test for '+21 45 567890 '
Shouldn't match the number

you are right, instructions are very bad
