Paid for service never delivered

Before starting my maternity leave I paid Awesome Moms for their service. They sent me documents to complete which I did and sent back to them. They then told me they would not be able to lodge my claim until January 2018. In January I resent the documents to them, reminding them to submit my documentation. I didn't receive a response, so I sent several more emails which were also ignored. I have phoned several times and the phone is not answered. I have SMSed and received no response.
