Unacceptable Turnaround Time and No Feedback

After 4 weeks I am still waiting for the claim to be finalized with my dreaded disease after my cancer has escalated to stage 4. There are 2 claims, one which should be a lump sum that should be paid out and another for temporary disability where the dr has booked me off for 6 months. Because my leave is not booked for 6 months the temporary disability claim now has been declined which we have appealed however it will take 45 working days for the Discovery Life Claims department to provide feedback. The other claim for the lump sum is just being ignored. It has been such a frustrating process, to say the least and so unacceptable.
