I placed an order on 17 April 2020 and received the order on 28 April 2020. Upon receiving my order and going through what was sent to me, I noticed that the one item which was delivered to me was incorrect, I bought a 600ml and a 400ml was delivered and the other issue I noticed also that two bundles that I bought from the More4less specials was charged at the full price. I called the contact centre and the first call (spoke to Nthabiseng) as I was talking the call cut then I called the second time (spoke to Kosi) and went through the items and at the end of the call she advised that I would be refunded for the More4less items and the item that was incorrectly sent someone would call me and they will come and swap out the item. I called again on 16 April to do a follow up as I was not contacted. The first call I spoke to Annalisa and I was asked for my order number which I started reading the numbers out and was rudely asked MAK? I was on a call with the Makro call center so I am certain it would be MAK, as I confirmed yes MAK, my call was cut! The second call was with Precious, I had gone through and provided her with my order number (and yes I did not include the MAK and it was accepted by Precious) however, again the call was cut. I gathered because I had provided Precious with my order number and the profile would have popped up she would at least return the call. To date I wait for this call and for a resolution on the incorrect item that was delivered to me. I am tired of contacting the call centre and nothing happens.
