Our group registered one domain (say for example
mysite.example) as it was shown available on various domain registrars. Registration went successfully on online payment. Even after few weeks it is also showing in registrar's 'Your domains' correctly.
However, if we check its 'whois', it shows with other bulk domain registrar with its expiry shown in December,2018 whereas we have registered the domain for few years.
If we visit that referred domain say
mysite.example, that bulk registrar shows the banner "for sale" there.
How can our registrar and other registrars were showing it as available in this case and successfully registered it too ? Will we loose this domain due to registration conflict ?
