State Bank Of India [SBI] — Refund is not credited in sbi bank account

Hi... I have booked goair ticket on 10-april-2020 for 19-april-2020 by makemytrip and payment was made by paypal due to lockdown in india the flight was cancelled and i talked to goair customer service they told me that company is giving 1 year reschedule time instead of refund but on 23-june-2020 flight ticket got cancelled and refund was processed to my source of payment from where the amount was paid. The source of payment was sbi debit card, but still i haven't received my refund amount which is 8779.70 in my bank account. Please resolve my issue as soon as possible.
I am sharing you the screenshots of payment made abd refund processed by makemytrip and paypal
