Verifying credit card

Hi

I got problem in my account for Apple Tv when i started to watch on my macbook pro. I subscribed TV first on my iPhone, 1 year for free and wanted to start watching also on macbook but system asked me to verify my payment card. As far as i have only debit cards i couldn't verified it because system showed that you're accepting only credit cards.

How can you help me with that issue ?

Looking forward to hear the answer from you!

Sincerely, Raimonds Roga
