It's been 5 years since I have the service with a cord blood banking company. Every year, they never sent me any invoices, I had to call them and paid over the phone by credit card before and around my son's birthday. My friend who has the same service but from a different cord blood banking company told me that she receives invoices once a year. At first I thought maybe because I called ahead (before my son's birthday) hence they hadn't sent the invoice yet. However, this year, I have forgotten about it, my son's birthday has passed for almost a month now, I still received no invoice. How do I verify if the company does not misuse the cord blood if they don't even bother to send me an invoice? Is the company trying to void the service so they can use the cord blood for their own research? Is there a government institution that controls cord blood banking companies where I could file a complaint or utter my concerns regarding the company?
