New number update taking FOREVER!!!!

I have been corresponding with Payflex since yesterday morning to update my new number on my account. They have now introduced a new system totally unbeknownst to their customers, where they automatically leave refunds in the customers payflex wallet. In order to withdraw the funds you need a OTP. So because my old number is still on my account I am unable to withdraw my funds, which I advised them and told them I need the funds urgently. Since yesterday morning my new number still hasn't been added and no one is responding to my emails. How long can it really take to update a number?????? This is pathetic!!! And please don't pit funds in customers payflex wallet!!! Return it to them the way they paid. You are making things complicated!!!!!!!
