Inccorrect sms details used

I don't have anything to do with African Bank. no account.<br> <br> I received a sms with someone elses account details and so forth. so I figured they have the wrong cell phone details.<br> I then called their call centre to arrange that the number gets taken off their system. so they wanted to get my ID number to escalate the query.<br> I have no clue why they want my ID number when I am not even one of their clients.<br> just take my damn number off the system. NOW!<br> I am not Ms ADAMS. <br> I hope I get a speedy response.
