Terrible Service!

I requested an renewal of my contract with a new Iphone 12 about 3 weeks ago on their Premium help desk. I was told to send an email to *** which I did. I got a reply to say as soon as the new Iphone is launch they would send it to me. After the launch date I heard nothing and followed up.. I was told they now out of stock and it is on back order... I asked when I would get my phone, and I got a one line reply, " You will have your phone by Friday" not Dear not thank you , nothing! Anyway that was last week Friday, which came and went. on the 28th I sent a mail asking what had happened to my phone... i got another one liner " your phone is on back order and you will get it end of January" again no dear, thanks nothing..... I rep**** requesting to have a supervisor phone me and the response I got was he is on leave. Is this the type of service you offer your Premium clients.. I think a total disgrace. Hence after 18 years with Vodacom.. time for a new provider!
