Hi Stephane and Anthony,
I am addressing your concerns about last quote in a forthcoming Email. However, I must initially express a real concern--We sent you invoice for 2nd payment 5-days ago, and we have already started your ED's stimulation. Our contract states that this payment was due prior to start of stimulation. Of course, we are now being billed from the clinic.
If payment has already been submitted, then please disregard this message. If not, could you please take care of this matter promptly.
