State Bank Of India [SBI] — sbi---refund not credited to my bank account

Address:

Sangrur, Punjab, 148026

I have an account in sbi, branch-bhawanigarh, punjab. I had made a purchase on myntra and i had made the payment from paypal through my debit card. Myntra has processed my refund through paypal on 11 th october 2019.in my paypal account, under the activity section, it's showing that the refund has been processed by myntra but that amount is not reflecting in my bank account. I spoke to paypal's customer care executive and they told me to contact the sbi bank. I spoke to the bank also but they are saying that they are not responsible for the payments made through third-party apps.
