Gems won't pay my bills or reply to emails

<p>Gems won't pay my bills even though it was submitted on time. Now they are asking me for proof that I followes up within 4 months of the service being rendered, so I sent them their monthly statements that they sent to me showing that the request for payment was pending and two months later my statement showed that I sent a duplicate of the account. So what more evidence do they need?</p> <p> </p> <p>Now that I have sent them copies of these statements they are not replying on my emails to inform me why they still don't feel like they need to pay.</p> <p> </p> <p>I am trully disgustes with this. My premiums are paid every month so why should I pay my doctors accounts when the accounts were submitted on time. </p>
