Shady dealings at Leratong Hospital

I have an issue with this hospital calling my mother who is a pensioner countless times a day demanding she pay R220 for taking my dad to that government hospital that I as a South African tax payer pay for. I want to know what this amount is for because no one said anything to her when she was there only now is she getting calls.They even have Maimela Attorneys now calling her and threatening her on the phone through their rude agents.I demand urgent answers regarding this before seeking legal counsel.
