Horrible Makro South Africa Service

On Thursday the 22nd of November I went online to buy some office chairs. Current price was R999.00 - original price R1599.00 Since I need an invoice to do payment through our finance department I phoned the Makro SA online number for advice - the lady logged into my account and agreed that something was not right. It might be a system problem. She will get back to me.. which did not happen. The Friday I phoned again requesting the invoice as I really don't want to miss the special. Again they will get back to me which did not happen. The Monday and Tuesday I phoned again... again still with no invoice. Now the price is back to R1599.00!!! I e-mailed the managers, Anthony Vermeulen and Lizzy Mazibuko with NO reply.. e-mail was sent out twice. So tomorrow will be 2 weeks since I first tried to buy these chairs, and I still don't have my invoice to do payment. Seriously, how can this be so hard? How is it possible to receive such bad service from a company so loved by the whole of South Africa. And it's not like I only wanted to buy one chair, the order is for 40 chairs. May now I will get some feedback. This has been a pathetic experience, I truly can't imagine the service I've been getting this past 2 weeks. Would like to thank Mbali Ndlovu who was the only person who actually tried to assist.
