Not able to confirm banking details

Good day.<br> <br> Since last Monday Old mutual has been unable to confirm my banking details with my bank, today again I called and was told that my initials do not match what the bank has. I am uncertain how that is possible.<br> <br> Kindly assist on a solution, as I am awaiting a pay out, and would like to know how much longer it will take.<br> I do not wish to be advised to call for an update in 5 to 7 days, I want clear indication now.
