Bad service.

I bought a wifi router at takealot on the 13 May 2022 and I received it but the problem was I wanted the ome with a sim slot. I got the wrong one and informed talealot. 17 May at 12h33 they cam to fetch it so they can give me the one that I was looking for or refund me. They sent me a ref number MRRN-X4D86NPM and a message saying they will call me in 2 to 3 days to confirm the steps to take. Since that day I never received a thing from them. I paid them R649 for the router.
