NOINVOICE,Handed over for debt collection for R100

I have been contacted by lancet laboratories/ampath. I have requested for the invoice and as of this morning i have been handed over for debt collection.<br> <br> I am a high powered executive and will not accept this, my attorneys will be notifed in the morning.<br> <br> but, long and short of it is that for - R100.00 i have been handed over to debt collectors because i refused to pay until i actually recieved the results and the invoice, further more i was not made aware that this company existed by the doctor's office and he probably charged me for this as well.<br> <br> if i am to pay a bill when i have no invoice, or transparent sight and receipt of product is this not a ****? it is absolutely unacceptable and the mere fact they did not have the decency to email me the invoice as requested is poor business practice and i am willing to take this further.
