Bad customer service from Makro online

I ordered a barcode printer and labels 3 months ago. My order was split into 2, the barcode printer was out of stock and they wanted to send me the labels only of which I refused. They refunded me for the barcode machine and tried to deliver labels and I refused to accept them. They were sent back to the manufacturer who called me to confirm that I didn't want to accept the labels only. Makro promised to refund me money for the labels. On 2 occasions they claimed to have refunded me apologized and promised to refund. I have sent over 4 emails getting a different person who tried to resolve the issue. It is 3 months later, I'm still waiting for my refund
