Vodacom blacklisted my device for unknown reason!!!

It was Friday 19th of November 2021 when I was having a social event with a bunch of my friends and enjoyed the afternoon. In one moment, my phone lost all cellphone signal to what I though it either load shedding or other network issue that does happen (I was in the connectivity industry). To my surprise, all my friends that were with me and are on vodacom network had full signal and fully functional cellphone service. Since it was Friday evening, there is nothing much I can do but wait for Saturday. I went to a Vodacom store and the over-confident consultant checked my number, took my sim card and tried it in an alternative phone - and it was all working. After, he referred me to the store since my phone is an iPhone that I bought outright. In iStore they checked all and said that the device has been blacklisted (?!?!). Going back to Vodacom store, I had to spend another 20-30 minutes explaining to the consultants that all is ok with my SIM card and number but the phone has been blacklisted. One more of the over confident consultants pointed me to fairways to get my device repaired (?!??) After demanding stubbornly for the to check the "blacklisting" system - they discovered that my phone is indeed blacklisted on vodacom network (!!!!!). I firstly demanded to know based on what and who blacklisted my device, but the system shows no trail, so I was simply "lucky" that someone just felt to do it for unknown reason. After, I was advised to do an affidavit, and send all the neccesary documents to unblack list my phone device. Waste of my time for absolutely no reason. Since I've done all of that on Saturday the wait begins - and still lasts - on Vodacom mistake!!! My reference for this is EC-1700-2HGQJB Vodacom - UNBLACKLIST my phone nobody has asked you to blacklist in the first place!!!!
