Is this a real number and not a  scam

I got texts from this #. They bought an item from me on ebay and it seems to be a scam. No funds were sent to my Pay Pal account and they wanted immediate shipment to Nigeria

I just got a text message from this number too! they asked me -
-my paypal email to send me payment for an "item" I'm selling on ebay.
-Provided the following email for photos and description? of this mysterious item I'm apparently selling on ebay: zara.sean@mail.ru
-when I asked where they got my number, they told me they got it off of ebay.
It's a scam!!! DO NOT give them any of your information. Ebay/paypal has put things into place to ensure you don't need to communicate outside of their secure server with anyone. Payment, communication, and security is taken care of by ebay/paypal. if anyone us asking you to comunicate and/or send them anything outside of the ebay/paypal server, you can be sure they are trying to scam you!
