No item received! No refund! ***** contact details!

It's been almost a year, ordered an item on Black Friday!!!! Eventually after going into the store twice and trying to do follow ups the item was out of stock.

Received an email, no signature nor contact details, email address doesn't even stipulate it's from Converse SA asking me for my banking details. Went back to the email asking for proof that the person is really where they said they're from and eventually she just ignored me!!!! Freaking pathetic service with no line of escalation!!! Where the hell is my money????!!!!
