Poor customer service

I placed an order on the mr price app on the 29 May 2021. The app froze when I already paid via their online eft. It did not place the order and now I am struggling to get any response from them. I send an sms to their whatsapp number that doesn’t work as well it is under maintenance and a few e-mails. Called three times. Got one of the agents, e-mail and sent the proof of payment but no response from that person. I phoned in again and hold for 40minutes, the lady told me she is gonna send me an e-mail and that i must follow the link to send my proof of payment. But while I was checking my e-mail to make sure she has the right address she put me on hold and the line went dead. I want my money back. The customer service agents are not helpful at all.
