Payment of a faulty order

I ordered online and part of the order was cancelled. No communication was done from Makro on the order part that was cancelled. I then received the other part of the order only to realise that it was faulty and had to return it. Ended up cancelling the whole order. Been waiting for payment of the money I paid and nothing has been done yet. Been sending emails and no reply from Makro. Its been a month.
