Makro Marketplace incompetency and collection of items

Makro marketplace is so ***********. The intoduction of it was a poor decision by makro. It has given me nothing but headaches since November 2018. Firstly they charged me 3 delivery cost for 1 order and then I asked them for to take back they order in November and till now they have only fetched 1 item which I still haven't been refunded for and the other 2 items haven't been collected. I have sent emails to Beatrice who is just ignoring me and not making follow ups and Tebogo the team leader at customer service who keeps promising to give me feedback everytime I call in, which is more than 10 times now. I have called in about more than 20 times and send through emails multiple times with no results. I have even tried taking the goods to carnival store and Thuxi told me that they can't take the products since it was an online purchase and can only be done through collection. She also promised to get the items collected and also said she will send an email to her superior Patricai and will get back to me, but no feedback given there either. What am I to do to get the items collected and get my full refund in order to part ways with Makro for good? I have spent a lot of time, money and energy on this. I am unhappy and have stress as no one is taking me seriously and they keep making false promises. What kind of customer service is this???? That it has to take makro about 3 months to collect items for full refund.

****ed!!!!!
