No solution or assistance... Poor aftersales service and customer care

I bought shoes for my son on the 20th of October 2022 but was struggling with the sizes because of the cuts of the shoes... I decided to take my son with me to change the shoes so that he could fit the shoes and ultimately get the correct size just to find out that the slip in the box was not the correct slip. I then called rage head office on the 5th of November around 11 but never got the agents name who had told me to go to the store for a reprint of the slip. When I got to the store I couldn't get a reprint because I couldnt remember the agents name that had advised me to go to the original store for a reprint. When I had called them again to explain my story and get a resolution, again, I never got the agents name and while explaining my situation she clicks her tongue and put the phone down in my ear... Now my question is... Since I can't get a reprint... Besides the fact that I'm getting sent from pillar to post... What do I do with shoes that I can't make use of??

In all honesty if this is the aftersales service of Rage South Africa then I don't want to submit my account application nor would I recommend them to other....
