Is anyone even attending to your generic mailboxes?

I've been struggling from the 3rd of October to reach one single individual who can help my re-submit my mothers' rejected claim. Numerous emails have been sent to which automated responses have been received (references are: ********** 520, ********** 572 and ********** 881) but NO form of any other feedback whatsoever. Emails were sent to ********** and to ********** . Every time I phone the 0860-number I am told to resend the documents. Is there really NO ONE who can SPEAK to me and tell me which of the generic email boxes are actually being looked at and the queries are handled? I understand that you have processes to follow for claims to be resubmitted but just SPEAK to your client and advise them of the correct steps to have their queries looked at!!! Can anyone please just give us ANY feedbac****!!!!
