Poor customer service

I have never experience a worse service like i did from multichoice in my entire life from any shop. I ordered a router with Sim internet data online. It was delivered on the 20th February 2024. Until today the data and Rica part is not done. What is frustrating most is that when i follow up i get different answers and empty promises that my matter have been escalated which non was done. It seems like the consultant doesn't know what they are doing. I have already spent total of 3 hours making follow up with no solution at my own expense. I was even denied opportunity to speak to manager on duty for a reason that she/he is on leave ir either meeting. At some point I was told to go to the branch which i refuse because online process should be end to end process.
