Paypal and Domainsite : Making me mad:( – Worries to register a Domain name!

My god.. I’m tired of the two services. All my domains are purchased from domainsite using an unverified paypal account.
Yesterday i was trying to buy a new domain. All goes well untill the last moment. In the checkout page I choose paypal and bingo, it failed with an error. I tried a few times but no help. The transfer is initiated but it cancelled without any fees..

I contacted Domainsite.com support and they cleared my doubts. They will not be able to process unverified paypal accounts anymore. Alternatively they suggest a work around. Send the money directly to their paypal account and contact again with details. I did so. After a few hours i got a mail saying that the money is added to my account credit.
Happy me.. But this time i select charge from my credit in checkout page. Err.. It also fails. They’re not giving any reason at all. .. So i tried to contact them again.. I mailed the support team with a detailed description of my issue. Today after 24 hours no replies and my problem still persists.
