cricket wireless won't let me disconnect a line Nationwide

 the first part of October I phoned cricket to shut my daughters phone line off becuz someone stole her phone at school. Crickets rep failed to disconnect instead they temporarily suspended it (I see why they did, so I would still have to pay for her line) Another billing cycle has now rolled around, I made a partial payment under their bridgepay program now they say the can't totally disconnect her line until my bill is paid in full, if I don't pay the bill in full my service will be disconnected. I already know that as crooked as cricket is it will be impossible to get a refund from them.. I also asked to speak with a representative from America and was told I had to go online to do so.
