Dial the right number,no excuses!

My partner and I have app**** for the access of the flexi funds on our bond. Submitted all necessary documents timely. 8days after the application we were told a verification call would be done to the co applicant which is me to finilise so we gain access. The number in which they called was wrong by 1 digit,we had that corrected and we were informed I should expect call following day,it's been 3 days and multiple corrections of my number being submitted via requests for call and they are STILL calling the wrong number! Are these requests even read? Because there is no way even after so many attempts they are still calling the wrong number. The number on my profile is correct so what source are they using to refer to my number when making calls? I am extremely dissatisfied with how this is being handled,it should not even be so hard. I am not a client of Fnb and this has guaranteed me never being one .
