Not cancelling deceased members subscription and still taking money from account

After my father passed away we informed Bonitas and requested that they cancel his medical aid both telephonically and by means of e-mail. They assured us this would be done and they would credit my mothers account for amount taken off after his passing. Not only have they not done it, they have taken another months subscription off her account.

My Mother has had to call them on numerous occasion spending hours on the phone with them. Disgusting that they put an elderly grieving widow through this!!!!
