Vodacome blacklisted my phone 'by mistake' and now it cant be undone

Vodacom wrongfully blacklisted my Samsung A12 I was using my phone one day and the next the phone did not work. Last weekend I went into vodacom Secunda branch. They advised the phone was blacklisted on the 22 May 2023. We were told to get a affidavit to unblacklist the phone. I never blacklisted the A12. No one at vodacom can tell me how it was done. Thursday 01 Jone 2023, a gentleman phoned to say he listened to all my recordings and it looks like it was backlisted in error. I could use the pone today because the blacklisting would have been removed, 03 june 2023. I tried using the Samsung A12 and it still did not work. I phoned and spoke to Simazo and she advise the phone was blacklisted and I must complete a form. I advised her I did and got a affidavit. I told her I did all that last weekend. She could not tell me the consultants name who blacklisted the phone or who phoned it. She has now esculated the matter and it will now take 4 to 7 working days just to listen to the message of the 22 May. At the time I was using my prepaid number in the phone which also got suspended. Untill then whoever blacklisted the phone is still unknown. I am still not able to use my phone because of vodacoms error. The service is useless, they dont listen to what customers requests and give false information. Totally discusted
