Can't receive calls or smses. TOBI is useless

Hi, I am not receiving smses or phone calls. I called your helpline but TOBI is really useless! I have been calling for a week but there is nobody who can help me. Also, I previously had someone attempt to do a *****ulent sim swap on my number and requested that you set my number to only be able to perform a sim swap by bringing my ID into the store for this number, however I see that that has now been removed and anyone can do a sim swap on my number again. Please note that if there has been any *****ulent activity on any of my accounts I will hold Vodacom accountable. Your customer service is disgusting!!! I don't even know how you are going to call me to sort this out because whenever anyone calls they get a "number unavailable" message. FIX THIS!!!!!
