Unauthorised SIM swop to get access to Bank acount

I will keep this story short, for the sake of other users. There are more than enough MTN reference numbers for MTN to find out what is going on.<br> On 5 Dec 2015, an authorised SIM swop was done on my wife's phone. After a few days I started to get One Time Passwords from our bank, On top of that the phone was dead. A SIM swop was done on her phone apparently in Graaf Reinett (we live in Pretoria).<br> Why?. Do the SIM swop to get the OTP requested by the bank, and we go to empty the accounts.<br> All MTN request for reports, documents ,etc. have been sent through FOUR times already, resulting in nothing but Ref numbers and 3 calls to Ghana, and one to Nigeria. We were extremely lucky that the OTP was not sent to the swopped card.<br> FICA? How did this SIM swap go through? Where are the documents? We have had the Royal get around for 2 months now. We need answers.<br> This can easily happen to anybody and cost you a lot of money!!!
