Making payment to one of two paypal credit purchases?

[Hm11mcf]

Hello, I currently have two purchases on my paypal credit account (£750 0% interest over 36 months, and £415 0% interest for 4 months). I have tried making a payment towards the most recent purchase as the 0% is only valid until April, however it has come off of the original purchase of £750 instead. Is it not possible to choose which purchase this payment goes towards? Do I have to pay off the first purchase before I can pay off the second purchase? If so, do I have grounds for complaint because I was not made aware of this and it's going to take me longer to pay it off now and I'll definitely incur interest charges?

Supposed to read the agreement. Go to the PayPal Credit Agreement and SECCI and read the payment allocation section.

Thanks for replying! I've read it and it says that it should go to the purchase with the lowest interest but they're both 0%, it then says in that case the payment will go towards the purchase expiring first. So the payment has been allocated incorrectly?
