No returned calls as promised

I am writing on behalf of my mother Asta Esterhuizen regarding her washer/dryer combo. The dryer stopped working. She called, and they asked for proof of purchase on 2/4/14 (which was sent Immediately via email). After calling a 2nd time 4/4/14 it was claimed that the email was not received. I then sent an email twice with the receipt in a .jpg AND .pdf format, which they claimed they could not open. While on the phone, they promised to call back. Which of course did not happen. So today we went to town to fax the proof through, and spoke to Henry to confirm - once again after being promised a call back no one has bothered to respond. We have spoken to multiple people with no joy. It makes things very difficult attempting to dry clothes at the coast with visitor. Please sort this out immediately as this is totally unacceptable. Please call my mother on the number provided.<br> Product ID: ***<br> Purchase Date: 04/06/2014<br> Slip No: ***<br> CCD No: ***
