Bill Pay with PayPal

I am trying to pay my bill online with my PayPal card and it keeps telling me there's a problem and it won't go through. Has anyone else had this issue?

There is a way to add TMobile to the bill pay section on my PayPal account but I need the zip code for the TMobile payment address and can't find that anywhere. I just need to pay my bill before the lines are suspended and it shouldn't be this hard.
