SUPER ANGRY

I am super frustrated. A sim swap was done on my number Saturday rhe 13 of March. I dont know how this sim swap was done as it was not me. It is an inside job because i dont understand how they got my details. They have been taking money from my account every till today on my Capitec account through mobile banking. Yes my pin was my date of birth juggled. Appearently this is a known thing as alot of people are complaining about MTN. How is a sim swap done without the actual owner of the sim. If it was done in a branch, dont you need my ID? If done over the phone, am i not supposed to answer questions about my recent activities? Who would know that information besided MTN officials.. Im super angry and want a callback immediately on my new number *** to get an explanation before I start a boycott against MTN. I will go public. Anelisa
