No feedback on return

My delivery from takealot arrived promptly but without all the parts that were supposed to be 'in the box'. In fact there was no box, but the item was wrapped in cling wrap, without protection. I logged a return on their website which was responded to with a request for photographs of what was delivered and details of the product barcode. There was no barcode on the product and I provided photographs of the product and the only code that appeared on the product. Since then there has been no more communication, despite a follow up mail from me. There is no contact number on the takealot website or on the email received from them. Unless they decide to communicate via email, I'm left with a useless product and empty pocket. This is not good customer service. If their intention is to avoid a large amount of calls from their clients, then its a good strategy. But surely, having noted that there's a return and having allocated a member of the team to deal with it, why is there no contact number???
