Not Receiving 2-factor Authentication Code

Hey guys - thanks for reading!

So I’ve been on the phone with apple over 8 hours cumulative now probably 7 different phone calls - here’s the problem:

I traded in an old iPad got credit (130) exchanged into a gift card. Put said card onto new apple id (because apple made me wait a week while my old id was being reviewed for fraud purposes as I tried to sign into my old id on my new iPad)

new apple id I credited with the gift card of 130 and 2 factored a phone number that was previously associated with another apple id - my dads

i logged out of new id and into old id on my new iPad when apples weeklong review was complete - I tried to log back into my new id to transfer the 130 credit to my old id but the 2 factor code doesn’t send to my phone (despite the last 4 digits being revealed correctly in apples partial reveal of phone number when you have apple send you a 2 factor code) - I’ve tried everything - texts calls etc with apple on the phone several different times and many hours - despite being told by the first two people this was a problem they can’t fix and my 130 credit was poof

the techie has identified its a problem on their end and she has escalated it to the programmers she assured me and sent the necessary info but I’ve heard nothing back from her or the programmers - at this point - nearly 5 months later mind you - I’ve lost patience with apple - how can I elevate this to the proper person so it gets fixed - ie give me the credit from my used iPad (130)

thanks again and sorry for being so thorough!
