Sales person not interested to help

I was at Makro this morning to buy 2 Defy aircon that is on Sale for R4699 with my father that just had a stroke and lost his eye sight. Me and my mom was standing infront of the aircon with Faiz and my dad came on asking where the aircon is and he said its here. My mom explained he can't see properly. We were told the aircon is out of stock. I asked him to contact M-Gardens and he told me they only have 1 but they cannot keep it aside for me. I asked if I could get a reincheck and he told me he wont give me 1 for the same value. I said but I came for it now and the special ends 25/01. He said its while stocks last I said it don't say that. And he said it does and I must go to the front to ask the people to buy it online for me. My dad asked him more than once what the amount is and I could see him get iritated (he is forgetful after the stroke) Got to C.Care and the lady said she cant buy online for me. Then Nadeema heard me and she came to the front trying her best to help me. She was so kind. real customer service. The aircon is not available online anymore BUT NADEEMA SAID SHE IS TRYING TO SEE HOW I CAN GET THE PRODUCT. I do think Faiz could have made a little for effort.
