Dealing with Discovery becoming a nightmare!

I am quite concerned with the amount of funds left on our MSA, in this short space of time between January and now. What is reflecting on the APP is also different from what is reflecting on the statement - which makes me wonder how the calculations are being done accurately. Secondly, I am also quite frustrated to still be waiting for the delivery of the medical aid cards after numerous requests and a hellopeter complaint where I was promised delivery of the cards within 5-7 days. Even now I am still waiting for medical aid cards, years later! Discovery really needs to get their act together - can someone from there tell me exactly what the difficulty is in sending the medical aid cards?! Is it that difficult a request and why promise delivery knowing very well it’s impossible to do so? Is it a cost saving issue to avoid posting or delivering the cards when you are charging your clients so much money a month?
