Vodacom is really no good at all

I had contracts with Vodacom and when the contracts expired I canceled all contracts. This happened last year (2019) now in March 2020 I receive a warning letter stating my account is due and they will take legal actions if I do not pay. This is nonsense because if the people actually did their jobs I wouldn’t be getting these emails. No wander Vodacom is loosing clients, it is because they are becoming one of the worst companies in South Africa. **************** man.
