Glymetrol natural health return product to brea ca make sure you get a tracking no. or else they will say they never received the bottles and then charge you brea, California

I ordered glymetrol back in december of 2009 and received 2 bottles in a copple of days. I called to cancel 30 free trial 7 days later because it made my blood sugar 180 I mailed back the remaining bottles 2 days after cancelling.  3 months later I got billed for  $109.60 and immediately called glymetrol and asked why . They said they never received the bottles in brea ca that I mailed  and asked If I had a tracking number I said no and had no reason to do so. so I have no proof I mailed back their product
