Appalling service - still no payment showing in my bank account after 3 weeks

It has been 3 weeks and still no refund is showing in my bank account. After numerous emails and phone calls; no help whatsoever from Takealot. Nedbank cannot help me as I am not their client; Takealot is. NOBODY at Takealot cares to pick up the phone, phone their Nedbank-branch and ask where is my money. Tried to explain it to Takealot-staff - did it help? No! Did they bother doing their part in contacting Nedbank, where they bank? No! Expect me, their client, who banks with ABSA, to try and sort it out. Not allowed = privacy act! And I am not a Nedbank-client. To say I am appalled by the lack of service is an understatement. I have been a client for a number of years now, and this is how you help someone who still hasn't received the money that is owed to her?
