Paypal — my refund taking long time.

Address:

132, Shivpuri Colony, Kalwar Road, Jhotwara, Jaipur, Rajasthan, 302012

I made payment to one of my friend in Connecticut USA on 27 July 2019 of small amount to check if everything is working fine and money goes on right place and it worked. after that I made payment of JUL
28
Urvashi Valand
Refunded – Money Sent
-$ 2, 282.24

and they did put payment on hold and said it will take 21 days to transfer the amount to her bank account.
Why???? if earlier amount sent to her bank pretty fast then why not this one... As she need that money on urgent basis and couldn't wait that long so she talked to paypal and asked them if she refund this money then how much time it will take to go in original payment source and pay pal said it will go in 3 to 5 business days for sure so she refunded it back ... now Paypal has refunded the amount showed on my paypal account now they are saying it will take 7 to 14 days or may be 30 DAYS OR MAY BE 60 DAYS!! so my comlained is if they can deduct the money as soon as i clicked then why can not send it back to me if it is already refunded. ??? and they are escaping saying its processing time ... so who will pay the interest for the time they are holding money?
on this they said they have refunded the money now your banking taking time ... and I talked to bank and bank said there no confirmation from paypal for payment... as soon as paypal send the money to bank it will be credit to my original payment source with in a second. now if paypal do not have money and neither bank had it then where the money gone????
