Question

Where to find Yahoo´s connection for changing card number

Answer 1

Call you credit card company.  Tell them you don't know what is going on.  From their end - they will have a customer service phone number associated with the purchase.  

I have done this before.

But thats my advice.  Otherwise you will be spending horrendous hours being transferred and leaving voicemails.

I hope this helps!
