hi,
I am from eurodns and I would like to help you improving registration with us. Additionally I will explain you the Creditcard issue all registrars have.
1. on creditcards is a lot of fraud, as soon thedomain is registered the registrar has costs which he can not get back.
so new clients are screened double to make sure to do not loose money. dont enter fake information like phone numbers 123456.
we try to call you some times, if you do not answer there is the risk that we refuse the order.
2. if you are a know customer at a registrar, please use always the same creditcard(s). In any case it is better for your controlling to use the same card at the same registrars.
3. prefund the account by wire or paypal. if your account is prefunded your registration is realtime. there is no second lost any more waiting for creditcard approval.
4. some registries queue the orders during night/weekend and process them during daytime. Example: France.
5. if you are a known customer ask your registrar to put you on invoice so that you can pay end of the month. we do this with some clients which have a nice amount of domains and which we know since a certain time.
if you have an issue with eurodns I am happy to answer your specific questions by PM.
