False Advertising and No Response to Complaints Sent To Head office

I bought a 2010 Macbook pro at their Doringkloof branch which was falsely advertised as a 2013 model.

I tried reaching out to the branch manager who became extremely rude and ask me to call whoever I want.

I wrote an email to their head office on the 17th of May and got a response on 18th that the case will be escalated and I will get feedback from a manager in 72 hours.

On 21 May, I followed up again. The person who initially responded copied the managers who are supposed to give me feedback including the owner of the franchise and the manager asking them to respond to me, even today 26 May, I have not received any response.

As a loyal customer, I'm extremely disappointed at how this has unfolded and how the uncaring attitude seems to prevail even when I've gone to the head office.

I need a total refund urgently.
