Solving ID disabled and "Please contact ITunes support..." issues

Question

After getting no relief from anyone at Apple support, I finally took the advice of someone who posted here and I wanted to reiterate it separately for those who are having issues.  I usually just download things from the ITunes Store to my PC and then I move it to my IPod when I have time.  And after many years of doing this, two weeks ago, I was blocked from my account.  First, I was told that my ID was disabled (NOT for security reasons) and once that was fixed, I still was told to fix my billing info every time I tried to download anything.  And after a few tries, I would be told to contact ITunes Support to complete the transaction.
After being given a special "free pass" to have the top techs talk to the lesser techs when no one seemed to be able to fix this, I still had no solution and the promised email to help me with my problems never came.  Finally, today while I was on the phone with them again, I decided, on my own, to do something another frustrated customer had suggested.  I connected my IPod and THEN tried the store.  It didn't work the first time, but on the third or fourth try, suddenly the Store knew me and let me download one song.
Since then, it's been smooth sailing.  So I guess the answer is to connect whatever device(s) you have and then try your download.  Don't give up after the first try, just keep at it.
