Momentum health disappoints again

I went for dental work on the 19th of Feb with pre aproval from Momentum health(from savings) I submitted the claim on the 3rd of March. No further communication was received apart from an automated email response. I followed up on the 11th of march saying was declined even though the pre approval was granted. I spoke to Bongile on the 17th of March at 8:45 confirming that the above is correct.
