Absurd billing, cannot reach the relevant department through various platforms

What a difficult exercise to try speaking to someone regarding an explanation of my absurd invoice. My LTE deal is R499 PM but my debit order is R1205 for July 2020, the account was paid for in June 2020 and was at a zero balance. I called *** and selected the option of assistance with accounts, the IVR notified me that "unfortunately we are not able to assist as we are not available". The self-service portal is out of order, it reads "session timed out" when trying to log a query for a call-back request (tried with both Chrome and Explore). I then selected the "technical" option and spoke to Bonga Botyeni whose supervisor is Sarrel Henn. Bonga could not help but escalate to billing through Natasha, who also escalated to Miranda of billing. I could not speak to anyone in leadership after numerous requests with Bonga who eventually hung up the line as I was refusing to hang up. It is sad to learn how MWEB lacks empathy to urgently assist frustrated customers. There truly is no customer service. Your service requires a great deal of improvement. Thus far, almost all calls I make to MWEB end up being a nightmare and it is a costly exercise. I need assistance and wanna be called by a manager and not a supervisor.
