@flyingphil172,

eBay have specifically set up the whole process so as to put complaints at arms' length. Self-evidently, they prefer not to deal with complaints personally, if possible. This is why almost everything on eBay is automated.

Pre-pandemic, it was possible to phone eBay CS reps, or to have eBay CS reps call you. Now, contact from an eBay member to an eBay CS rep is almost exclusively via Live Chat. The standard of CS rep manning the chats is not very high, in terms of their level in the food chain, their expertise, ability to overturn decisions, act with autonomy, investigate non-standard situations, and/or provide remedies to complaints.

Members may possibly be able to request CS managers via Live Chat, but it will depend on the circumstances and the member's ability to communicate courteously and present a clear case.

There are other bodies to which complaints can be made, but the complaint may end up floating in the wind, or require more than one complaint, or give nothing but moral satisfaction, or not be the best way to handle the situation.

If you give even a vague idea of the situation about which you'd like to complain, the experienced responders here will at least have some basis for advising you about how best to proceed.
