I've subscribed for a year, yet haven't recieved any thing

Hi, I've paid for a subcription for a year still my device says I do not have any plan or subscription hence it is not recording. I've tried to email, tried to find they chat window couldn't find it, I've tried to call but my phone doesn't ring it up don't know why it immediately shuts the call down. That's why I am reaching out here, can anyone help me? Sincerely
