Bad customer service from ASAP!

I placed an order on Saturday the 4th of December and was notified that I needed to replace my items as they were out of stock. Unfortunately I did not see the notification in time to replace the items and my order ended up being cancelled. Since then I have been calling but unfortunately I have not been lucky enough for my call to be answered. I've emailed and sent contact forms all to no response. I have no idea if my refund is being processed because Pick n Pay has not had interest in responding to me.
