[de2014.shis]

Hello, 

I'm new to Germany, even though I understand German I am not able to speak enough of the language yet and explain my problem to the eBay customer care on phone, I bought on article load month for Which the seller did not ship the item. I made ​​a buyer protection case against him and won the case (case what decided in my favor). I have received a mail Stating did I have been refunded the amount. This mail came to me 3 days ago. Please help me out with a few queries 

Firstly:

The payment method I used When buying what direct debit. I have checked my bank account statement since then, I have not received any refund from eBay. I do not know how long it takes Refer. (It's been more than 48hrs)

Secondly:
I read on the buyer protections - refunds tab, did I need to have a paypal account to Obtain a refund. Is this mandatory? i will not receive a refund without a paypal account?

Thirdly:
I opened a paypal account through eBay now and have linked it to my account. Should I contact eBay again to send me the refund?

Thank you
