Ning.com Ning Network I subscribed, they sent zero email invoices.

Tools like siftery and truebill.com should detect these subscriptions. 

It didn't. 

They've constructed their invoices in a hosted manner to where they don't send email invoice notices. 

You cannot cancel the subscription digitally, that's a tell-tale sign of a bad service, one where they make lots of money on breakage. 

If you're an acquirer looking to buy a company, this company has fake metrics that are juiced by breakage. 

Start sending email invoices to customers and you'll find immediate churn. 

Bad and terrible support.
