Vodacom blocked my line and no one can help me get it unblocked!

I had my line suspended on 9 November 2020 and have been struggling since then to get it unblocked. I've called many times through to your call center and even went into the store and no one can help me. I've sent emails, written letters, sent copies of my ID and still nothing! It's now 17 November and I am still unable to make or receive calls or text messages. Can someone please help because this is affecting my work. How do you simply block a line without any notification and no one can help me to unblock it? Simply unreal. Your customer service is absolutely appalling. I've been a customer for over 20 years and never had my account in arrears, all I ask for in return is a line that works. Shocking!
