My friend wanted to purchase premium account. I requested him to purchase it while downloading one of the files uploaded by me. He has a paypal account. When he clicked on one month premium account buy button and entered his paypal account details, it asked to fill up credit card details. Even after clicking on skip button it asks for credit card details. He is verified paypal user and has got sufficient balance to purchase one month premium. This thing doesn't happen while purchasing 90 days premium. Can we not pay by paypal for one month premium without providing credit card details?
