Hello,
I just bought a 3 month premium service and did the payment via pay pal but my account is still a trial account and I can't use the upgraded options. could you please check it out and let me know about it?

Hello Seyed,
Thank you for your question about the upgrade. We investigated as soon as you wrote, and made the correction needed.
At the time you wrote, PayPal had a notice posted (for us) that IPN's (payment notifications) are a bit behind. We regret that you were affected.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
