Unauthorized sim swap and *****, 3 weeks with no answers!

It has now been 3 weeks since there was ***** on my account. I have had the same number on the same network for 15 years. Out of nowhere a sim swap was done on my account and the *****sters took out a R350 airtime advance. Luckily i found out was was going on quick enough before they did more damage. What i want to know is why do i RICA a simcard and Vodacom has all my personal details but allows someone to do a sim swap pretending to be me without any proof? Furthermore it has now been 3 weeks since the incident that i am unable to load airtime or data as any airtime i purchase gets deducted from the advance the *****sters took. I cant work and make calls to clients, you are killing me. Why does it take over 3 weeks to get resolved? And for the *****sters to be able to answer my security questions they would have had to have access to my info, which i can tell you now nobody has which allows me to believe that this kind of ****ming is being done from inside your company. This needs to be settled asap so i can carry on with my business and life!
