Frustrated with Hospital Network Corp.'s lack of response

I'm writing to complain about the troubleshooting service I received from Hospital Network Corp.. After paying $940.82 for item, I found that it had my warranty claim denied unfairly. I've tried resolving this with your customer service team multiple times, including speaking with Lula V., but have not received a satisfactory resolution.
