Can't register a domain even if it is available :(

[wxdqz]

Hi,I have been eying a domain and it recently got available on networksolutions and register.com. I paid for it on network solutions and next day they sent me a mail saying they could not register the domain and will refund my credit card. it then became unavailable on both the sites.After 5 days, it again became available. I paid for it again on networksolutions.com and it has been over 36 hours and I have not recd any mail from them rejecting my application. However, the domain still shows as "available" on both the sites. I paid for the domain again (3rd time) just in case.Anyone knows what's been happening here.PS:the whois status for the domain is ***this domain has been suspended***The site is "Not Available" on godaddy.com
