EBAY $30.00 promotional credit fraud towards a new ebay mastercard. Nationwide

The message said if I chose to pay by the EBAY card, i'd be credited $30.00 towards this purchase. I appl EBAY $30.00 MASTERCARD CREDIT OFFER SCAM UNKNOWN

EBAY offered me a mastercard with a $30.00 credit towards any purchase through March 30th 2015, while I was shopping on EBAY for a dog collar. I applied and I was approved instantly online. Then when I asked to make my purchase o this new card, i was asked to wait till the card arrived. The card arrived weeks later, leaving me just two weeks to see about my purchase. so when I tried to purchase the said dog collar, i was declined, not once or twice but constantly. I called PAYPAL that the card was linked to with a phone number, than I got transferred to EBAY, which bounced me back on PAYPAL again, saying the card may not've been good for that particular purchase, but it is good.

At last i found out the said EBAY MASTERCARD was not good toward any purchase!

I wonder if the card would be good after March the 30th, when the $30.00 promotion is ended, but do I realy want to use that card again!
