I need a refund for an ebook I purchased on the wrong account and cannot find any help anywhere.

I was trying to purchase the book and didn't realise I was on the wrong account until after making the purchase. I then requested a refund for the first purchase and bought the book on the correct account. ... I purchased an ebook through Google Play called The Return of Absent Souls: After the Rift Book * a few hours ago on the wrong google account and requested a refund. I then purchased the book on the correct account only to receive an email saying I'm not entitled to a refund on the first purchase I made. I believed I had forty eight hours to request a refund and it has only been roughly twelve hours since I made the purchase. I've tried calling customer care but the number doesn't appear to be valid when I call. I can't seem to find anywhere that gives any decent help as I'm not sure how I'm not entitled to a refund, according to the policy.

The email I received informed me I'm not entitled to a refund despite being well withing the time limit mentioned for getting a refund due to accidental purchase.

I simply need a refund for an ebook that I've purchased twice now.

I've tried calling the customer service numbers but my provider informs me both numbers are invalid. I've tried another refund request only to be told the same thing, that I can't get a refund. I'm still well within the time limit.
