Shocking customer service and feedback

My spare cell phone has been blacklisted by Vodacom for no reason, as my account is always paid on time via debit order. I have submitted all supporting documents, etc. to the blacklisting dept. which then referred this onto the accounts dept. Noting I only use this cellphone on a pay as you go sim so this should not even be a factor. This has been on-going since the 09/09/2019. I have tried to call the customer care line several times over the last month where the call gets cut off continuously, 4 times today alone (17/10/2019), mid-call while waiting for a customer care agent to answer, which then puts you in the back of the queue when you call back. The online chatbot is down for upgrades, the live chat is down for upgrades, the link to the accounts dept. email address does not work and the email that was originally sent to *** is no longer being rep**** to. Vodacom I know you monitor Hello Peter, so this is now my last option, Please HELP!
