Makro double pricing consumers on orders

I purchased a gas hob from Makro in Polokwane on 16/8/2018. They advised that they don't have stock and will have to order it. On 23/8/2018 I recieved a call from the sales lady informing me that they charged me the incorrect price and that I need to pay in an additional R900. I refered her back to her manager and said I paid for a gas hob and expext delivery. She called me again saying that her manager can only agree to me paying an additional R700. I then contacted Makro's Head Office complaints on 23/7/2018. They transferred me to Eddie. I explained all to him. On 24/8/2018 I had to cal him back as I havn't heard anything from him. He then said that I said that I'll go to the Makro branch after 15:00 on the 23rd and that's why he din't cqll me back. Only then did I realize he is the branch manager at Polokwane branch where my complaint originates and that Makro H/O complaints transfers you back to the applicable branch. No use of having a H/O complaint line then. If I call a H/O complaint line it is due to the fact that I' not getting joy from the branch and have exausted all avenues of resolution at the branch allready. Eddie then informed me that the best he can do still is that I had to pay R700 additional. I said that it's not acceptable . I will now revert to CEO complaints, Facebook, CPA ect. Moral of the story is according to the CPA i paid for a gas hob and now Eddie tells me that I only paid a deposit and not the whole price. Strange that they insisted that I pay for the hob before they could order it on 16/8.
