Still no feedback

<p>I initially logged a claim on the 11th July 2016 as I had not had any feedback after dropping my documents in the box at the hospital on the 2nd June 2016. After 10 days without response, I called the call centre (***) and was advised to send the documentation through to the claims adjustment department. I sent the email on the 21st July 2016 and received an automated response saying: We have received your amended account request and will process this within the next 2-3 working days. Your reference number is ********** 962. Another 13 days pass and still no feedback so I email again on the 3rd August 2016 and receive and automated response: We have received your amended account request and will process this within the next 2-3 working days. Your reference number is 46013****8. So now, I am sitting with 3 reference numbers: 4uuvyG, ********** 962 and 46013****8 and still no response. Should I email the claims adjustment department until someone responds? </p>
