Does Vodacom punish customers who cancel their internet service contracts?

Does Vodacom punish customers who cancel their internet service contracts? Vodacom abruptly suspends my internet Fibre connection, prematurely. Reason given by them in response to this query, "it was a mistake". At the beginning of the month of January 2023, we informed Vodacom of our intention to cancel our subscription for their Fibre internet service. The reasons are not important here as it is our right out of choice. The intended end of service was the 1st February 2023 as indicated on our request. After several attempts to dissuade us from this right, they finally acknowledged our request in writing via e-mail. However, on the 27th January, at around 6pm, we found that our internet service was no longer active. We called them and the response was that they would sort it out. After several calls which we made daily thereafter, we finally received an e-mail admitting that it was a mistake, which to date has not been rectified. I believe that this serves as a punishment for us because we no longer wanted to continue with Vodacom as a service provider. This is besides the fact that they are more expensive than other service providers in the same industry. Disgusting, isn’t it. Hereunder is a copy of the email sent to us on the 28th January, 2023 in response to our disgruntlement. ‘Good day Your query has been escalated to the second line team as a matter of urgency, As I have communicated on our phone call that the order was mistakenly deleted on the Openserve portal, we have escalated for a reload and reactivation. We are actively working on restoring your line. Your reference number is SR*** Kind Regards
