Vodacom customer service sucks!

Terrible customer service and *********** staff from senior management level to entry level. Requested for Fiber service cancellation in August 2019. Cancellation would have been effective 01 October 2019. I was given a service cancellation request number (over the phone) SR***. I was advised that all was sorted. The last debit order should have gone off my account in September 2019. However, debit orders for R 955 have continued to go off my account up until now (May 2020). And the reason for this, as per a customer service representative I spoke to on 09 May 2020 is because I was sent a cancellation email last year and I never responded to - that email would have triggered the final deactivation. How on earth was I supposed to anticipate/expect an email from Vodacom that would activate cancellation if the agent I spoke to in August 2019 never mentioned it to me in the cancellation call in August. I just loathe how these South African companies have *********** staff (junior and senior levels) and continuously take advantage of the customer at any cost. Anyway, after I tried to contact Vodacom numerous times last year (with no success), I sent an email to the Vodacom CEO in December 2019. This email was diverted to a Vodacom staff who attempted to contact me in December 2019, missed her call once, I responded and she went mute. And the debit orders have continued to go off my account till now!!! I am at loss of words as to who to blame...incompetence of the customer service agents who are managed by *********** managers and *********** executives!
