T-Mobile Experts aren't experts. What can be done?

How do you determine where they are?

I usually open the T-Mobile App and click on the "Call Me" and their auto-attendant rings me immediately and I am connected to an agent. Perhaps, because I had been given a pre-paid account instead of the post-paid I asked for, I was getting a foreign call center rather than domestic. Though, since changing the plan to post-paid and attempting to upgrade to ONE Plus three of the four agents I spoke with had a strong accent and tended to be unfamiliar with how to apply this plan option. Only the last one contacted, Paul, spoke with what sounded like a US accent and he quickly established the Add On for the T-Mobile ONE Unlimited 55 plan.

I noticed last night in the T-Mobile App it now shows a

     "T-Mobile ONE w/ONE Plus Family Unlimited 55"

where the day before it was

     "T-Mobile ONE w/ONE Plus Unlimited 55"

and the day before adding the ONE Plus it was

     "T-Mobile ONE Ilimitado para mayores de 55"

I guess that the "family" aspect is something that was just implemented, and it now matches what the rather argumentative agent in chat was telling me was the reason I couldn't get the ONE Plus for the Unlimited 55 plan.

The bottom line is that there appears to be a consistent issue with training, supervision, and attitude toward helping that is evidenced in customers being unable to get relatively straight-forward issues resolved in a timely manner.
