Complaint Review: Amden Corp (Cybersonic toothbrush)

I purchased a cybersonic by phone. It arrived and did not care for it. I returned hte toothbrush expecting a full refund I did but only after several nasty letters and contacting my credit card company. Now they keep sending me my free brush replacements for only 4.65 a pop. I can't find a phone number to contact them anywhere. Can anyone help me out. I would surely appreciate it.
