Today I received two "Domain Name Expiration Notice" from Domain Renewal Group. I do not own those .com domains (so no renewal) but do own the equivalent .co.nz... Obviously they are going throgh the NZ DNC WhoIs and getting domain owners' data to send these out.
If you receive those DO NOT PAY. The text at some point says:
"Privatization o Domain Registrations and Renewals now allows the consumer the choice of Registrars when initially registering and also when renewing a domain name. Domain name holders are not obligated to renew their domain name with their current Registrar or with the Domain Renewal Group. Review our prices and decide for yourself. You are under no obligation to pay the amounts stated below, unless you accept this offer. This notice is not a bill, it is rather an easy means of payment should you decide to switch your domain name registration to the Domain Renewal Group".
