FNB assigned my ID to another person

I wanted to open an account with FNB so i logged my details on the FNB website to switch my account from another bank. Later that day i was called by someone from FNB telling me that someone is already using my ID number. I then went to the Eastgate branch where i scanned my fingerprints and indeed i was confirmed to be the owner of that ID number and the admin manager told me i must wait for 7-8 WEEKS! for the ***** department to investigate. Who in their right senses will wait for that long knowing that someone else could be tempering with their identity.<br> I then called the complaints department and told them my issue. I was issued with a reference number (700392NF) and someone called me a few days later telling me that FNB and Wesbank did a mix up when they linked my Wesbank profile (registered initially with a passport) to my ID number.<br> <br> I just need this to be resolved and i can know that my Identity is safe. <br> <br> I am even having second thoughts about moving to FNB after such a lackadaisical response even before i open an account.
