maya invoice idgi !!!

hi po, this isn’t a CC related inquiry but I couldnt find a better community to ask, I just received an email from Maya, “Here is your invoice for the payment covering your loans with Maya Bank, Inc.”. I just settled the loan payment yesterday, and I’m just unsure since the amount in the invoice is lesser than my loan payment kahapon. though the email subject is “Invoice for payment last Oct. 16”.

babayaran ko pag ba to? or it’s like a receipt of what I paid yesterday? for context, I paid 3k++ for the loan, and the email invoice billed me P1k something. huhu im so confused. help pls 😭
