Don't accept VISA Debit Card

So I keep getting an error on there website when trying to book with my debit card.

I want to book 3 tickets to 36 CrazyFists, I tried a few times, and at my expense I have to call there helpline just to find out that they Don't accept debit cards, what bull**** is this.

Everywhere else I can use my debit card but not at computicket, I refuse to have a credit card now I must go to a checkers and book, this is not right.

I am disgusted with this fact, I actually don't know if I even want to go to checkers to book.
