Handset discharging gummy, sticky black drainage

I am a new users with 2 handsets and both of them seem to be defective. One will not hold a charge or allow it to be registered. The other one registered okay, but it sat in the charging cradle today and when I picked it up this evening, there was dark, sticky, gummy discharge on the end of the phone that sat in the cradle. I call customer service and they say they have never heard of this. I am not really impressed. I have had the service for 3 days and both the handsets need to be replaced already. Has anyone else had this kind of discharge?
