Issue not resolved

<p>I went to Standard Bank (Wonderpark Mall, Pretoria) to go change my number so for all my banking transactions, I specifically said I wanted my number to be changed for EVERYTHING. I left and they said it bwas done. I gon home and tried to pay Unisa from the mobile app and the one time pin went to the od number. I wengt back to the bank, I repeated that I wanted my number changed for everything and they told me that the oeson who helped me before was supposed to make me fill out a form so that my one time pin could be sent to my new number. When i left the bank they told me it would take about three ours and then i can make payment. I am at home trying to pay my fees and the pin was sent to the old number AGAIN, when i call standard bank they tell me I must go back to the bank. I dont understand why i need to keep going to the bank for exactly the same thing. This is waisting both my time enegrgy. </p>
