A few years ago I registered a domain name with company 'A'. Later I registered another name with company 'B' (They simply provided a better service).
In the mean time I got company 'A' to change the tags for the domain name to be for company 'B'.
I have just received an email from company 'A' telling me that my domain name is about to expire and needs renewing. Who do I renew this domain name with? Is it company 'A' who I originally registered it with or is it company 'B' who I changed the tags to?
If you changed from company 'A' to company 'B' to host your site, then company A should have let the people responsable for registering you domain name know that you have changed Agent, so go back to company 'A' and tell them the error of their ways. These are the terms of Nominet: click here section 5.4 relates to what the agent should be doing.
This is what should happens when its time for renewal click here
