Refund D2 purchase please

Hi Blizzard
I cant launch the game, even after reinstalling 4 times, did the repair, followed all the procedures several times, opened a ticket, etc… lost several hours now
I want to have a refund at this point !
Please Blizzard contact me to initiate it or ill simply call Visa and cancel it and leave after 17y i am not satisfied at all with this bad delivery quality.
you guys should meet and see why all this is going on, bad preparation is my only word right now.
So please refund.
