Terrible service and rude Manager

On the 24 May 2022, i noticed that i had not been receiving calls or sms notifications, i called cell c's contact centre the agent informed me that my account was not paid, i informed her that i have debit orders going off my account how is it possible that my account is not being paid, she went into the account and saw that the account was paid and it was an error on their side, apologised, and unblocked the account. On the 28 May 2022, i tried making a call and again my number was blocked, i called the contact centre again, and the agent Hulisni, informed me that my account was not paid in June 2021, i went through my financial records and saw that the debit orders went off my account, the agent could not help me and i asked to speak to the manager, my call gets directed Mr. Allearf, and he told me i need to sort it out with acounts and the only way he can help me is if i pay my account. I have two debit orders that go off for cell c every month and had not missed one, i do not understand why my account was blocked twice in one week, if my account was not paid in 2021, i would not have received a notification in March 2022 for an upgrade and my number would have been blocked the same time the payment was not received. It is now almost one year later Cell C is following up on a so called outstanding account that is being paid on time. This is terrible service, i am looking into changing my network provider.
