Momentum Health - not living up to the benefits they claim to provide

Momentum, over the past couple of years, has seemingly started trying their absolute best to not provide their patients with the cover that is legally (as laid out in the medical schemes act) and contractually available to their clients! https://www.medicalschemes.co.za/resources/pmb/

Particularly when it comes to PMB (prescribed minimum benefits)! Prescribed Minimum Benefits are additional benefits, laid out by medical schemes. Momentum, every year, providing less and less treatment coverage for their clients, giving fewer treatment codes, and giving shorter time frames on treatment authorisations (if enough coverage is even provided for these auths). It is becoming increasingly difficult to deal with Momentum and you are sent around and around from one consultant to another until you give up. Patients who are sincerely ill or who genuinely require certain treatments are not getting it because of these hurdles, even though they pay for the coverage.

I am tired of emailing and phoning Momentum over and over, for numerous different clients that just getting nowhere.
