Phone blacklisted by mistake for a whole week by Vodacon

My phone has been blacklisted for a whole week. I have phoned Vodacom twice, went twice to the stores, emailed them twice. No one is helping me. I went to the police to get an affidavit, sent them all my required details as per online.

Nothing. I have been without a working phone for a whole week. No one is helping me. I did not blacklist my phone- I am the owner. I do not know why nobody wants to help me. What should I do ?? Best network in SA? I think not.
