Poor service and communication

My aunt, Mrs Dooka had a knee operation at Folateng Hospital in March 2009 and the hospital has been owing her a refund of over R800.00 since April 2013. She has been send from pillar to post and she made a lot of trips to the hospital to have the refund to be paid. Eventualy she was informed that the refund can only be paid to her daughter who currently lives in Switzerland as she paid the hospital bill. In January 2015 was in the country and tried to get the refund paid and her efforts were futile. She wrote an affidavit for the money to be paid to Mrs Dooka as she was going back to Switzerland. The refund is still not paid and she was informed that they can only pay into the bank card that was used to pay the hospital bill. The problem is that the card has expired and replaced with the new card even though the account is still active. It will be appreciated if Folateng can pay the refund amount to Mrs Dooka with interest as it has been over 2 years since it has been outstanding. An urgent response to this matter will be appreciated as this is long overdue.
