The products are of different value and therefore they can't be swapped without issuing a full refund on your original purchase. Because the original purchase isn't refundable by the refund terms, I'm afraid I can't offer that option.

Thank you so much for the offer and being flexible ! i've talked with the creater. And he suggested me to wait for the new update. For me, i feel like the optimal solution is: pay extra for a p2p instance or keep the f2p. If there a way to pay extra to upgrade too a p2p instance ?  

Yes you can 🙂

Can I use dream bot if my accounts are using jagex account?

Generally, the same refund terms apply to script swaps as well. Therefore, this purchase would not be refundable or swappable. However, there's one outcome I'm willing to offer to you. The value of this lifetime F2P instance is $32 and the value of 2 monthly P2P instances is also $32. Because the products are both from Aeglen and he is ok with the swap, I can swap the lifetime F2P instance to a month of 2 instances of P2P. I'm afraid I can't offer any other outcomes. @dragon1337, let me know if you decide to keep the lifetime instance of F2P or if you want to accept my offer to swap it to 2 P2P instances for a month.
