I love tmobile. I've been a customer for 16 years. That bring said this app is ridiculous. I can sign in 10 times and I'm still not signed in. Now i now you've merged but the fact i either have to pay more as a guest or call or go to the store to pay my bill is getting ridiculous, especially right now when I'm medically hampered. Please fix this app right like you take care of everything else.
