Have you tried simply cancelling membership according to the T & C's?
Membership cancellation
2.1. You may cancel your eBay Plus membership at any time by selecting โManage membershipโ on your eBay Plus membership page and then selecting the โCancelโ option in the drop-down menu.
2.2. Other than in the circumstances set out in clause 2.3 below, if you cancel any time after becoming a paid member or your membership automatically renews at the end of your membership term:
2.2.1. you will not be refunded your membership fee regardless of whether or not you made any eligible purchases or have taken advantage of any eBay Plus benefits since your latest Plus membership charge; and
2.2.2. you will continue to receive all eBay Plus benefits until the end of your membership term, but your membership will not be automatically renewed for a further term.
2.3. If your free trial membership or annual membership renews automatically at the end of your membership term and you are charged the annual membership fee, you will have 14 days from the date you have been charged on your preferred payment method to request a refund of the membership fee from Customer Service. For the avoidance of doubt, you will no longer be entitled to the benefits of your eBay Plus membership from the date of cancellation.
