Request a refund But did not get the full amount

On 2/5/2021, I have requested a refund in All 12 reportaproblem.apple.com requests are approved. And i have received my money back But I only got 9 of the 12 refunds, will I get the rest? If not, why not?

(This is a refund request document.)

(This is the receipt in my payment app.)

There are 3 items missing.

From my investigation, there were two orders with more than one purchase, which were missing.

1. This purchase order 3 items refunded, but only received 1 item.

(The amount required to receive is ฿87.00)

(But I got it for only ฿29.00)

(The amount required to receive is ฿178.00)

(But I got it for only ฿29.00)
