Ebay Plus $30 Gift Card to renew

Hi,

 

I took up the offer of a $30 Gift Card to renew my Ebay Plus subscription as I initially did not want to renew.

 

When I renewed and paid $49, I did not receive a Gift Card so queried with customer services.

 

Then I was given a $30 voucher (not gift card), and the expiry is 1 month from issue! Not 3 years like a Gift Card.

 

I have contacted customer services many times and they say they cannot extend the expiry date.

 

Any one else with the same issue? And who  can I escalate this with?

Thank you.
