Disgusted client

I am being taken from pilar to be post by Bonitas. I had submitted a claim with 2 weeks from the date of treatment. I sent them the claim for processing with all my details and claim in question attached (proof available). I got email notification acknowledging my email. The following month I followed up as there was no one getting back to me. My follow up email was "complaint" asking for feedback - they responded with "claim is being processed" a year later and 8 months claim still not paid. Consultant from Bonita ( Denis) asked for all the evidence that I indeed submitted the claim on time. I sent all the information he requested. Then he comes back to say "I didn't query" claim within 6 months. The audacity for them to tell me that I didn't query about the claim within a 6 month, they overlooking all evidence present to them, is it really fair to take clients for a ride like that? With everything I have done on my side? Claim submitted on time, followed up on this claim, still you have the audacity to tell me that my claim is stale? How is stale? What have you done from your side? Is this how you treat clients because you feel you can do whatever you want? I am disappointed to the core, I have no words. You are so evil,
