Double deal Iphone not existing

I app**** online for a Double IPhone deal on the 14 June 2022, got approved called in was told I will be called back. Waited after 2 weeks I called in,was told the deal is finished,they offered me single deal confirmed everything even delivery, I waited till today no delivery when I call in I am told Tsholo must call me, me phone are pit down, today I decided to call I was told the phone is no longer available. Vodacom why do advertise false deals and never call customers for finalizing. Can you sort out my deal as I want what you advertised. Very bad service
