No airtime? We'll call you within TWO days.

I called in to FNB and told them that I have been retrenched and I need to change my cell number with them to another number (my personal cell) they told me that they had changed the number but now as I'm trying to use online banking my OTP's are going to that number I REMOVED. That number which I removed is now in my bosses hands. I am trying to load my personal cell with airtime now so that I can call FNB QUICKLY but I have no option to do so, the OTP just keeps going to my bosses phone (my ex-cell number) So in desperation I requested that FNB phone me urgently, to which they rep**** online by saying, \We'll call you back within two days\" I need assistance NOW, not in two days time!!! I'm guessing that I'm going to get a call from them because of this complaint sooner than I get the call which I actually requested from them. Lets see."
