Is there any way to get TMobile to STOP SPAMMING my phone?

I get announcement after announcement from T-Mobile telling me to open an account with their bank. I am not interest and responding STOP to get off their mailing list doesn't work. I never signed up to be spammed and I use the T Mobile Spam Blocker app on my phone which doesn't help a bit. Does anyone else know how to get TMOBILE to Stop Spamming? It is really frustrating.

I will be contacting the FCC if it doesn't stop. They may not be able to do anything, but if enough people complain, they will at least investigate which will undoubtedly cost T-Mobile more than they are getting by hounding people to open a Bank account with them.
