Vodacom a MESS!!!!!!

So Vodacom had an error on their side and forgot to take a debit of my ban account a couple of times and this has happened a couple of times now. I recently spoke with one of their agents that rectified the Debit day but did not really rectify the matter. Vodacom Penalizes their clients if debits do not go off accordingly regardless if it was their mistake, All the agent wanted to know is when the best day will be to debit my account... Sad. After rectifying a matter that never should've happened I get 3 automated calls from Vodacom telling me to sort out my account... This has become an invasion of my personal life and even in the earliest morning hours, I get these automated calls. My next step will be to take legal action against Vodacom for invading my personal space and bombarding me with calls that should not even be going to me. Vodacom your organization standards have seriously dropped and you should be embarrassed. Vodacom is a big JOKE
