Meural purchase overcharge

I tried to buy two playlists, got charged 6 times and recieved 6 invoices - 5 for the same purchase.  Invoices are from a noreply account and no other contact information.  I cannot find anyway to contact Netgear to get this resolved.  Also my purchases are not showing up in my account.

One charge pending on my card is for all 6 charges. 

Does anyone know how ai can get through to Netgear and get this sorted?

Hell of ay to run a business.
