No payment

Ive been struggling for a month to get my money back. No reply to emails and Every day i phone there's a new excuse, from the internet is done to they lost my banking details. I phoned every single day for the past week and a half and every day Pieter (the manager) "assured" me that he was just about to sit done and do the payment. Ive been very patient with you but its getting ridiculous now. When can i expect payment?
