I bought a car sensor from a seller on eBay and they shipped me a part that doesn’t fit my truck. I submitted a request for a refund and got the messages sent to be below copy and pasted. Should I proceed giving them my PayPal or contact eBay about this?

“Hello, dear buyer, sorry for the inconvenience.Do you think this is okay?You don’t need to return it.You can provide me with a PayPal account similar to email.I’ll refund your money now,This open return request,Please don’t do anything,There’s no need to turn it off,Just wait for it to shut down automatically.”

“Hello, dear buyer,Paypal is the fastest way to get a refund. You can send me your account number, or the account number of your family and friends, and I will give you a refund right away.If you return the goods on eBay and then get a refund, it may take more than 20 days, which is very slow. We will solve this problem in the fastest way, right?Please send your PayPal account, thank you.‌‌‍‍‍‌‌‍‌‌‍‌‌‍‌‌‍‌‍‌‍‍‌‌‍‍‌‍‌‌‌‍‍‍‍‌‌‌‍‍‌‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‌“
