Very bad customer service

My daughter placed two orders online with Makro on 2 March and 7 March 2025 for Stanley cups, first order was 1 Stanley for R1200, and then on the 7th she saw they were on sale for R700 and decided she can buy two for almost the same price as the first order and will return the first one. Although in the comments people was mentioning that it is **** Stanley’s, I told her that Makro SA is a established renowned business that will not sell **** items, well were I wrong. The first order came, ****…we went to Makro Cape Gate, trying to return, they said we need to return online as it is a online order, we did ask for a return…the second order came but only one of the teo Stanleys that was ordered, **** again, she logged in a return and was able to cancel the other Stanley that was still outstanding. After waiting for more than 3 weeks for the collecting of the Stanleys, Courier Guy finally came and I gave them both Stanleys, the one of the first order that was R1200 and the R700 one from the second order, we emailed Makro, letting them know we send both back together. They refunded the R700 one but not the R1200. Since then I phoned, emailed them but nothing…apparently the Stanleys is from teo different suppliers and I should not have send them back together but separately, now they don’t answer me anymore, and I still haven’t received my refund for the **** Stanleys Makro are selling. I expected more from Makro. Hopefully someone see this, which can help me and I will gladly provide you will the invoice details and so on.
