Shocking Account Management

My dad has needed various home therapy after suffering from a stroke in February. Moto Health have made so many errors on his account. Continuously paying providers from the wrong account - his savings account has therefore been completely finished... I have been struggling on a daily basis to get the PMB payments done correctly. It is now August and they are still busy with April. They have no idea what care goes into a post-stroke patient and just cannot get his account sorted out. Last month I spent hundreds of rands phoning them to sort out his account - we are still nowhere - I am paying for the the******s in the meantime - no idea when we will be reimbursed. I have tried complaining but one cannot get near management. Their service is pathetic and I wish I could move my dad to another medical aid. They owe us thousands of rands and I just cannot get these matters resolved! I want someone in senior management to contact me. I am done dealing with *********** case managers and administrators who just don't know what they are doing.
