Sorry, you can’t currently place an order online

I wouldnt know the answer to those questions in regards to max lines and such but I would have assumed someone has checked that. Ive been told multiple times cases have been opened to review but have never received a response. I've only been a customer for 16 months and I'm on the military plan. If I select a phone device it gives me the same error message. However if I want to add a watch, tablet or any other device like that they will let me the specific deal I wanted was available last week online only but after asking customer service to honor it for me since I can't shop online they said sorry we can't do that. It is an endless loop of frustration and all I want to do is spend money.
