Makro Carnival

I made an online order at Makro and purchased 3 small items from the Makro website on black friday. 1 box with all the items where delivered. Firstly I could not log on to the site as it kept saying my credentials were incorrect for about 15 tries, then when I went in it would not accept my card for payment which I also tried multiple times until I changed payment methods to EFT. Due to limited stock most items I wanted to purchase where sold out and did my purchase quickly to get my items on times, so did not check the slip. Upon reviewing my order I found that I was charged 3 delivery cost for each item but delivered on the same day. I called Makro and gentlemen I spoke to told me that they will reverse the fee. Then he called me again the following day to inform that unfortunately they cannot reverse the extra fee because the orders come from 3 different suppliers hence 3 delivery fees. I then decided to go to the store to find out what's happening. I got to the carnival store and when I got they struggled to get my invoice for about 30 minutes and only to find out that it linked to a different online exclusive store. Then I was sent to department that deals with online orders and they contacted Fiona from the store and all she had to say was that she is sorry but cannot refund back the fee as it was from 3 different suppliers when I asked her why is it that its not stated on website or t&cs about that? she says that they don't usual disclose that which is why its not on the website. I mean when a customer purchases online, on a specific website she expects the product from that store. How they get the items should not be the liability of the customer but theirs as the store. Fiona then asked Tshuxi to call Trevor who will explain the policy to me. Tshuxi could not get a hold of him and this an addition 30 minutes that we have been waiting. Tshuxi then informed me that she will send an email to Patricia and they will call me back with regards to my query. This is the worst service I have ever encountered from Makro (Tshuxi did all she could) and fact that they do not disclose all important information is a direct CPA and FAIS violation. When I asked Fiona why is it that it not on the t&cs on the website, Who can I contact to help me with this case?
