AVOID NETREGISTRY AT ALL COSTS! Deceitful and fraudulent behaviour, shady cancellation policies, dodgy auto-renewals and absolutely zero care for their customers.
Netregistry insist on charging my credit card for domain privacy for domains that I no longer own.
I've been a customer for 6+ years. After a week of trying to resolve what should have been a very simple thing to fix, I'm now instead cancelling all my business with Netregistry as quickly as humanly possible and warning others to stay WELL away!
If you take a minute to Google around, you'll quickly find many hundreds of other angry customers complaining about Netregistry's dodgy cancellation and auto-renewal practices. Trust me, it is no coincidence that Netregistry have such an overwhelmingly large amount of 1-star ratings on various independent review sites, such as productreview.com.au, trustpilot.com, hostadvice.com and many others.
In short, whilst you can let a domain name expire without any issues, Netregistry have (very conveniently) decided to have a completely different cancellation policy for add-on services, such as domain privacy. It's right there - hidden within 70+ pages of fine print, well beyond the reach of both logic, morals and common sense.
Netregistry will happily continue to charge you - despite not actually providing a service. When asked why I should be paying them for domain privacy for domains that I no longer own, there is no response other than pointing to their T&Cs.
So unless your life is just going TOO smoothly and you're feeling desperate to add in some more frustration, bullshit, complacency and deceitful business practices to spice things up a bit, I recommend you AVOID Netregistry!
