Bad service / *********** staff

I am so disgusted with the service I received from Discovery Health. I am currently in my self-payment gap so I went to the eye specialist who prescribed eye drops and a cream for my eyes, went to the pharmacy to collect the prescribed goods, pay for it in full. I scanned copies of the script, invoice and proof of payment to Discovery just to get an e-mail back that the document's I supp**** are not clear, missing information, etc. I then phoned the call centre, spoke to the first agent who told me the script is not clear. I phoned the pharmacy and asked them to send me another copy which I then send to Discovery. Again I received another automated mail stating the documents are not clear missing info etc. I then phoned the call centre again, could not speak to the same agent so I had explain my entire story again, this agent then tells me another story. Apparently the pharmacy is not allowed to stick their sticker on the scrip. What?????? I have never heard such bull. She then advised that I must phone and get another script without a sticker. Clearly she doesn't have a clue and I don't understand how Discovery can have such *********** people working there.
