No payment and no correspondence

I am seriously considering going elsewhere for medical aid due to bad service.I sent in the initial claim on Tuesday 6 January .Two days later on Thursday 8 January I called in to confirm that they have received all the required documents and that they could also see all details clearly for the claim to be processed. I was advised by the call center agent that all is in order and that I should receive a payment by Monday 12 January 2015. When nothing happened I called again on 14 January to confirm what the delay was.The next call center agent initially couldn't find my claim but when I told her that that was impossible as a few days earlier someone found it, she suddenly found the claim. She then promised that she would personally check up on my claim and keep in contact with me as the claim was now completely delayed. She asked me to re-send my claim to her \manager"who from day one was clearly uninterested in me as he has been reading my emails ( I have read receipts) but has not responded at all. I then sent another chaser on 16 January and then again on 2 February but guess what"
