Lancet - unprofessional

My daughter was hospitalised last year and blood tests were taken. At no time between then and January of this year did we receive a single invoice or statement from Lancet. Then, in late January, they called her and asked her to pay – immediately – an account she did not know even existed! I then took this up with our medical aid, which subsequently informed me that they had NEVER received this claim (or the second submission that Lancet says they sent). They asked me to contact Lancet again and ask them to provide proof that the claim was submitted. This took over two weeks. We called and emailed Lancet several times to get them to do this. NOTHING WAS DONE. Then, my daughter emailed Lancet again and asked them to send HER the proof that she can forward to the medical aid. During this period – while we were waiting for Lancet to submit proof to us - they rudely handed the account over to debt collectors. Last Friday, 21 February, my daughter was FINALLY emailed proof from Lancet, which she immediately sent to the medical aid. Monday morning... the debt collector phones to demand payment. The medical aid will review this – it will take time. This is now a stale claim and it won’t take 48 hours to process! I find this very underhanded behaviour by Lancet. After taking almost a whole year – and never contacting us about the claim or submitting an invoice, they suddenly want to rush the process. We should be afforded the time to have our medical aid review this claim - one they DID NOT receive previously. If you need bloodwork, stay away from this lab! They don’t treat people very nicely.
