Worst experience ever

I have a very traumatic mountain bike accident late last year, my Medical Aid was amazing Momentum paid for everything except the Anesthetist in full, I submitted my claim with Stratum and got a return stating "You will receive feedback from our Claims Team within 10 working days" I had to follow up as my claim was never even captured, I had to constantly follow up with them, the representatives were always extremely helpful but I felt everything was a fight, the payout was eventually made by Momentum once again and I believe Stratum paid a fraction - this is still to be seen as it has not yet reflected. I have no idea what I have been paying towards for over 10 years. I have submitted a claim for another procedure and I'll see if they are of any help, if not I will be cancelling with Stratum.
