Makro customer service is horrible

Unhappy about response from Makro I have been conversing with David Mabena about my query. The las response from him was that the is no evidence that my daughter brought the laptop at the Milnerton store. I rep**** stating that the person who attended to my daughter when she was there was not competent because she said to her she will make a note that she brought the laptop but my daughter was not given any reference number. Secondly I told them that on that day my daughter didn't have the invoice and the Makro personnel printed it. So Makro should check their cameras & even the printer work for that particular day. Thirdly my question is, what is the life span of the battery, is it less than 2 years. To date Makro has never responded
