Handed over after two weeks!

I went for blood tests on 16 October at the Lancet Intercare branch, through my medical aid - after I and another person had to wait for 30 minutes for the receptionist to give our requests through to the sister, I was assisted. Now two weeks later I get an sms to say that my account has been handed over to an attorney! After two weeks! I haven't even received an account or sms to say what is payable or that it wasn't paid by my medical aid. This is not the first time that this has happened. The service and customer relations from Lancet is not up to standard.
