I'm stubborn enough that given what they have said and what you have now remembered about the transaction, I would try again. I would probably do something like:
Hi...to whom am I speaking? Hi xx, my name is Vickie and there seems to be an issue with my account. Before we precede, I want you to know that I've had some time to go back through my emails along with what information you have been allowed to provide and know that it was my ignorance that has created a suspicious circumstance that warranted suspending my account. If I may, I would like to relate what occurred on my end and see if if that matches your records.
On XX date, I won/made a BIN purchase for Essential Oils from XX company (transaction #). After not receiving my items by XX date, I filed a "goods not received" with eBay. I finally received the items on xx date, but I didn't correct the status because 1) there was no prompt to do so and 2) I didn't know I was supposed to. I soon discovered that the Essential Oils were not as described and that I needed to return them. Not knowing exactly how eBay works when it comes to returning items under these circumstances, I 'cancelled' the bid thinking that that was the correct course of action. I was finally able to contact the seller to return some of the Oils to the seller and receive a partial refund.
Now not long after I 'cancelled' the bid, I received an email from eBay saying that my account had been suspended. I honestly thought it was one of the 'spoof' emails that try to get you to click on their link and then steal your information when you log on so I sent the email to eBay's security team. I was in the midst of retiring and had a new grandchild so when I never heard back from eBay I forgot all about it.
Then on xx Date when I went to see if I could find a replacement part for my vacuum cleaner on Ebay and discovered that I couldn't log in. I've gone through several 'chats' and even tried speaking to someone on the phone, but no one will tell me anything other than my accounts has been permanently suspended and that they couldn't tell my why my account was suspended "because I might use the information to circumvent the suspension".
At this point, I'm pretty angry and upset. I've never broken a law in my entire life, I'll pay all my bills and in a timely manner. I haven't used eBay much and it wouldn't bother me not to use it ever again, but because of the horrible treatment I have received by eBay, it is now the principal of the matter. And since I am retired, I have plenty of time and resources to correct this situation.
If you are unable to help me sort this matter out, then I would ask that you transfer me or give me the name and number of someone who can.
If you get nowhere, then set an alarm every day to call. And let them know that you intend to call EVERY SINGLE DAY until this issue is resolved to your satisfaction.
