Atrocious service for 1st claim, no assistance

I am trying to submit my 1st claim with Zestlife gap cover for my hospital bill for the birth of my child. It has been over a month now , I have requested consultants to call me back to find out about my claim and the progress. All I got was emails saying documents were missing. Which I then got from the hospital and gynae and sent to Zestlife. I had to call the call centre over 5 times to find out about my claim. Each time something was wrong with the docs i sent or the consultant couldn't see the attachment. Everytime they requested new docs I sent it to them within 1/2 days. No one ever called me to explain what was missing / wrong I had to call the company time and time again. I got an SMS and email today to say my claim is rejected as they didn't receive all doc's which are the docs i already sent over and over again over the course of the month. I am paying over R400 pm to this company and my claim is approx 13k yet they do not have the decency to even give their customers a follow up call to explain the process or what the client needs to provide. I am so disappointed with this service I have sent all the documents now and is any my claim to be reviewed. Thereafter i will be cancelling my cover with this company . This level of service is atrocious.
