Only able to add one child

Good day to all.

Purchased norton family to have the two kids web and cell activities "watched". Added kid 1 with no problem. Added it the the two computers and his cell. Everything went perfect. Went to add the 2nd child and that's when it all went down hill. Every time i try to add a 2nd child i get a red error on the top of the screen stating unable to retrieve activities followed by the error "details provided is invalid"". I have tried every combination of names and ways to make it work. This started approx 2 weeks ago. I called into "support" they attached to my computer and attempted to add the 2nd child with no luck. I was told that they needed to send my information and a ticket number over to the enginering department and I would receive a "call back"in 24 hours. 24 hours came and went and attempted to add the 2nd child again. Same errors again. Called back into support to get the issue fixed and had someone attempt to "fix" the issue again via my computer. No luck. Was told a call back would happen again with in 24 hours.. No luck. 

Well now 2 weeks later of doing the exact same routine day after day I'm at the point of boiling. I paid for a service that Norton can't provide. Is there other people that can have more than one child on the account? Does this product work at all? Is all the reviews and hype all for nothing? Can someone actually help me?
