blocked number incorrectly by a consultant

Vodacom blocked an incorrect line and now they don't want to assist by unblocking it, I called vodacom now to block and blacklist my sons number as it was ******. They went and blocked the wrong phone. When i call them to correct their mistake they tell me i need to go to a vodacom store. Im currently under quarantine due to covid. Does that mean I wont have a phone till after I'm cleared of the virus? I need this resolved urgently as I cannot stay without a phone.
