Sim swop and number unlock

Never in my entire life have I been so inconvenienced by a service provider before. My life has come to a complete stand still because of Vodacom. I have been going to the store multiple times for them to sort out my sim card and get it unblocked. It has been a full week and I have received zero assistance let alone response from Vodacom. I have been using the number when I bought my first phone over 10 years ago and the one time I need help Vodacom just refuses to assist. It is my number. I have given them all the necessary documents to prove that the number belongs to me and all I'm getting is nothing but inconvenience. I am frustrated and furious. I need to access my emails and pay my bills and they just don't seem to care. Vodacom do better please! I have been calling the store where they said,they have sent the email for my number to be unlocked and still nothing has been done. I use to work for Vodacom Shop and I have been trying to get my number unlocked and nothing has been done the whole week.
