Difficult to speak to real people.

Dealing with this company from South Africa is a nightmare. You cant speak to the call centre and the entire webpage is bot operated. I ordered a product from USA to ZA. Product was faulty. They replaced it very easily and quickly. I was asked to return the item on my own expense and they would refund me. I paid R1400 ($79) to ship it via DHL Express. When the item arrived they refunded me $20 for the shipping. I have tried to query this but trying to speak to someone or not get an automated response, takes miracles. I need someone to respond to me to get the rest of my shipping refund.
