Please help.. Viagogo problems costing me thousands

[KOPV]

Hey please someone help me. I have been up all night first trying to buy tickets through ticketmaster.uk then after it sold out I switched over to Viagogo. It keeps giving me an error message each time I try to buy tickets. the ticket prices keep going up thus far they have doubled from when I was first trying to purchase. I get to the place order screen to finish and complete and it tells me

Authorization failed. If you believe this to be in error, contact Customer Service.


I'm all ready "varified visa"


HELP!
