Rude staff members

My medical aid was suspended because the debit order went of a bit earlier than I thought it was going to be. I made payment on the 4th February, and tried emailing it to ***, but it kept on coming back returned. I then went onto your online chat and spoke to 2 different staff Lebang and Masentle: I explained to them that the email was coming back returned the whole time and I also wasn't getting through to your customer services, and the automated message was also we have high call volumes. I then eventually got through and spoke to Eugene. He then went to that department and asked them for the pdf I sent through to them, and he was told they didn't get a pdf from me. I did sent it. I have now resent the pdf on the online chat to Lebang (speaking for the 2nd time), only now after holding on the phone with Lebang and resending the pdf proof of payment, Eugene has got it sorted for me. I really didn't like the way it was handled by Lebang or Masentle.
