Extreme poor customer service and lies

As from 18 Nov 2021 when I initially reported the extreme poor customer service received from Vodacom as well as their misleading adverti*****t, I had to supply them with the evidence regarding their misleading adverti*****t on their on line site on 22 Nov 2021. Vodacom however reported that they have send me an e-mail regarding the matter which is a total lie. The only e-mail I received was the request to supply them with the evidence of their misleading adverti*****t, which I did and of which I have proof that they received and opened the e-mail. More than that nothing happened and it seems to me like if this is a case for the NCC.
