INCOMPETENCE FROM LANCET!!!

Lancet in Nelspruit took samples from my wife when she had an operation in December. They put the incorrect date on the sample and when they tried to claim from my medical aid it was obviously rejected, because the date was incorrect. Lancet then sent me the bill, wherin I pointed out their mistake to them. After some profuse apologies, they told me not to worry about it, they would rectify the dates and resubmit a claim. They informed me to ignore the messages demanding payment as this was an automated system and they would either call me or email me when they resolved the issue.

Fast forward 6 months, they changed the date, but did not submit the claim, " We are sorry Sir, we don't know what happened on our side, we will submit it now" is what I was told. Finally a couple of days ago I get an email saying "Please be advised that due to the age of the account, we are unable to claim from the scheme however the member is more than welcome to submit from their end." And now they are demanding immediate payment from me!!! NONSENSE!!, due to their own incompetence, they created this situation, now I am supposed to pay for it???
