worst upgrade experience ever!!!

I wish I could rate negative stars! I app**** for an upgrade on 24 November 2020 - for a package that comes with 2 devices (P30 Lite) . Today (15 / 02/2021) I still have no feedback . My contract has expired and my current phne is faulty , the second device was also meant to be a christmas present for someone . I cannot even begin to desribe the amount of calls, Twitter messages ect I have had, mostly with no responce !!!!! apparrently for almost 3 months now there is no stock!? how was something offered if there is no stock . MTN blames the online outsourced company, and they blame MTN in return. No one can help me, and the MTN stores just say sorry we dont deal with online!!!! Last week I got a call to say we have stock in a differnt colour ,I agree and they advise I would get it today . I call again today to be told there is no stock again. MTN what is going on, the lady i spoke to then has the cheak to tell me I can cancel and select another phone.... there is a reason I selected that offer- due to budget and 2 devices . I have never had suck bad service in my life, MTN is the worst service provider there is, with no assistance or compassion for clients, but there is nothing wrong with my money you take!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
