Lancet
Handed over to SCS. No invoice received

My wife received sms notification that her account information (Ref V2692440) was handed over to SCS attorneys for not making payment. We have not received any invoice for the outstanding amount. Furthermore, 2 tests were conducted after this specific test, but we received invoices for these test - which was then paid in full.
I phoned SCS to state my concerns, but I was told that they only handle the debt collections, and that I should take any concerns up with Lancet. SCS then agreed to email the outstanding invoice to me. I am still waiting for this email.
My wife later receives another sms stating that to "Avoid further action pay R167.70 TODAY at Nedbank ###". We have since made payment, but we are still awaiting the invoice.
I take offence in the fact that legal steps where taken againts my wife, even before we knew there was outstanding monies.
