Vodacom agents misrepresent information in order to prevent

Decided to cancel contract 2 weeks ago. Called Vodacom and a guy called Ashley convinces me to upgrade to an I7 Apple handset as I told him I am going to another network that can offer me a good deal. I explicitly ask him if they deliver during lock down and he said yes it will take 7 working days. Decided to surprise daughter with phone for birthday. After 7 days passed I called only to find out from another agent they have been out if stock since Feb Keep on calling them to rather cancel contract but now they say the Ashley guy must do it left numerous messages for him to call or ask consultants to ask the manger to give me a call but nobody from Vodacom gets back to me in the meantime they put charges on my account.
