Non-existent Service!! Couldn't care less attitude!

I have been dealing with a sales agent called Bongani Mchunu who practically nagged me to upgrade 2 of my numbers- emailing me constantly until I eventually responded. He confirmed my upgrades on 3 February 2021 and I received the copies of my new contracts that same day. He assured me that my new phones would be delivered within 5-7 working days. At the latest they should have been delivered by last Friday (12.02.21) but I haven't received them. I emailed Bongani twice to query this but received no response. I then sent Cell C a direct message via Twitter on 15.02.21 explaining the situation and got a quick response asking for details saying it would be looked into. This morning, I asked to be updated and received the bland response that they have a backlog of queries and will get back to me as soon as they can. Seems Cell C couldn't care less that one of their agents seems to have gone AWOL as no explanation has been given for his lack of response, and they just don't care about actually dealing with the issue with any type of urgency. The lowest level of service delivery!! In fact - non-existent!!
