Linking T-Mobile account with Mint

I want T-Mobile Money bank account to be linked with Mint financial application. Unfortunately, T-Mobile Money account no longer shows up in Mint! 

I checked with Mint customer care, their response is as below. Seems, T-Mobile needs to respond but unfortunately, there is no response or no interest from T-Mobile technical team to allow this integration.

Response from Mint customer care team -

"I have located T-Mobile Money web address in our system, it should show for you to add the account but it was removed in 2018 because of connectivity issue. Unfortunately since 2018, all T-Mobile affiliated websites have been blocking our script from accessing our customers information so it is no longer supported. This just means, most commonly that Tmobile isn't working with us in order to resolve. But since the case is still open that means we are still trying for our customers.

We are working on the matter, but cannot move forward without Tmobiles help. That is what's holding my engineers back unfortunately. Other than calling them and notifying them of the issue, there is nothing else that I can think you can do to get the ball rolling with Tmobile.

For those who want T-Mobile - Mint integration, I request you all to send email, message or call T-Mobile customer care to request them to allow this. Otherwise, they have been sitting on this issue since 2018. All major banks like BoA, Chase, American Express all such integration with highest possible security and responsibility. There is no reason why T-Mobile shouldn't join the league of great financial insitutions.
