Discovery a disgrace!

I cancelled my medical aid with discovery and it was brought to my attention that i am owing discovery and whereas Discovery has been getting money month in and month out. Worse part of it all I need to pay my doctor a certain fee because Discovery could not pay him.

The was a time Discovery was unable to cover my other medical expenses but money is going to Discovery month in and month out.

Now that I have cancelled my membership with Discovery, why must i pay?

Please advise.

What is the next step forward because I am not willing to pay that amount of money. Something must be done.

Besides how am I going to pay Discovery now that I am unemployed?

Please advise.

Thanks.
