Disappointing medical aid

I have been a member of medihelp since 2017 diligently paying my membership fees on time every month. Not evens when I was retrenched due to Covid a year back and my husband's salary was cut did I ever miss or skipped or delayed a payment. However every time when I am admitted to hospital their is always issues regarding payment of service providers. I was admitted to hospital on 30 Jan 2021 through ER. My condition was related to PMB benefits which according to the council of medical schemes should be covered in full by my medical aid however this was not the case. This after numerous same issues regarding payments of medical bills by them. I than app**** through my gap cover to pay the shortfall of which it was declined and advised that my medical aid should cover the full cost and if they don't they need to supply a valid reason in writing as to why the account was only paid at Medical aid tariff. We pay medical aid to have the benefit of having medical assistance and peace of mind when falling ill but one is always more ill after being treated because you need to stress about bills not being paid and use your own time and money to call and email after them to not get assistance or being ignore and process being delayed! I would appreciate it if management can take the time to sort out this issues because the bills needs to be covered!
