Vodacom reluctant to cancel contract

I am referring to the last reply made by Vodacom on the 15/4/21 that they have rep**** to me privately well I don’t know but I haven’t seen any written reply and I’ve gone through my mail there is nothing from Vodacom The only interaction I have had with Vodacom since I wrote the review on the 13/4/21 was a phone call inquiring what the line number was that I was complaining about and they informed me that they will be investigating the situation and come back to me. Up until now 21/04/21 I am still waiting for the feedback I have been hearing “We will investigate” from Vodacom since Feb 21 when I first raised the issue I’m just wondering how long it takes to investigate the situation
