Can't receive or dial out and cricket wants full payment for bill on the 15th of every month

I have 4 lines and none of us can dial out or receive calls, my father is diabetic. He could get sick and die. He can't dial out for help and I can't reach him. Cricket won't help. I am going to seek legal assistance for failing to provide services but still bill me 100% for services I do not have and cannot utilize. This is a effing scam. I'm switching asap. The phones are trash. I keep all of my phones in cases and they all burned out and never turned back on after 3 months and had to purchase new phones at full price all over again. This company needs to file bankruptcy and stop false advertising their services.
