Vodacom continues to block their own customers without Reason

I wrote a review about Vodacom last week as they incorrectly sent me an invoice for approx. R30K. A week later, and it is not yet resolved. According to their social media manager, they are suddenly unable to email me a statement and claim they are unable to reach me by phone. I'm unable to use their chat service or call them as I have been blocked for calling the call center "too many times" . As a loyal Vodacom customer for over 20years, I cannot call or use the WhatsApp chat or customer service because I called "too many times" to try and resolve an error that they made. My only communication to them now is via social media chat, and they refuse to provide me with an indication as to when my number will be unblocked so I may use the appropriate services to obtain my invoices and statements. Vodacom you have to do better than this. Very disappointing.
