Refund issues

Description

Hey, so I sold something on depop but the buyer wants a refund for the product (it was £90). The buyer requested the refund on paypal, making my balance -£90. I tried to add funds to my account but it wouldn’t let me, so I instead decided to directly send the buyer the money. When I went to send her the money, the £90 was automatically applied to the total that I would send, so I only sent £0.85, making the total £90.85. However, she only received the £0.85, but the -£90 on my paypal balance has been cleared. Will she receive the £90 in a few days, like is this £90 pending because it was through a refund request? Please help me because the money has come out my account but I don’t know where it has gone
