Incorrect Billing and Unauthorized Debit Order aka THEFT!

So after months and months complaining about the poorest service one can find, I thought my complaints have been resolved in April. Billing errors which have been acknowledged and corrected and now in May miraculously I'm being charged for a migration fee to a package which was confirmed should have been corrected as a fault on their part. I was guaranteed that this ongoing problem since November 2023 is resolved. Clearly the saga continues. I'm now being billed AGAIN for competence. This is theft! Vodacom you are despicable and ***********!!!!! Taking money from people is unacceptable and what I find most disturbing is that you can bill correctly at end April and now I'm being billed in May. The other disturbing part is I've put a block on my debit order in March and somehow you manage to over rule my instructions and take my money without consent. This is how you treat customers from over 20 years. I cannot WAIT for my handset contract to come to an end. Clearly NO customer service, customer centricity, customer anything in mind. I demand a refund and NOT a refund to my account. A refund to my bank as you took my money WITHOUT authorisation for a debit order. *******!!!!!
