Uverse Account Has Incorrect STPs Ser #s

Recently (~ 4 weeks ago), I requested a WiFi extender. In the original order, they sent a new gateway along with the extender.  I informed AT&T that would not work, as I needed a gateway with coaxial connections.
They replied with "Try this" and wasted their time and mine sending out new other STPs (Set Top Boxes) that would not work for our application.

I was finally able to speak to (1) someone where English for which English was their 1st language and (2) he was Tier -II support. He informed me that we could use our original gateway. AT&T was mistaken in thinking they needed to send out a new gateway and the three "replacement" STPs.

So all is good now, correct?

Well, it was until just returning from vacation and finding none of our STPs work. The error is "This Set Top Box does not match the account settings"

After placing two calls and finally overcoming the language barrier, I was able confirm my suspicion.  AT&T changed the serial #s listed on our account from the old S#s (all have been in place for years and were/are functional) to the new S#s.

And they're saying they can't correct the S#s in the account, we have to wait for a tech to be rolled.

So now, AT&T has wasted their money and my time (1) sending out units that were not required (2) paying UPS to ship the non-required units back to themself (3) wasted money on the packing boxes of the non-required units (while at the UPS store, they pull the STPs out of the boxes, scan the codes, and trash the old shipping boxes (4) are rolling a truck instead of just letting me read off the S#s on our STPs and updating our account records.

Is there no one I could talk to at AT&T that could merely update our account with the S#s I would provide, and fix our problem, save themselves the truck roll?
