Problem with eBay Seller!

I bought 6 items from a Spanish seller on eBay - some cuttings and some plants in pots. I received a small parcel on 9 July, which contained a plastic food box, with one cutting (Avonia) and one Echeveria Topsy Turvy in a pot. I assumed the seller had sent two parcels, so I waited a while, assuming the second parcel would surface soon, but after a couple of weeks, when it still hadn't arrived, I wrote to her, to let her know, and asked if she had sent two parcels. She wrote back to say, yes, she had sent to parcels, and to let her know when "I" arrived ... obviously meant to say when "it" arrived. (Probably used Google Translate ...) So a little over a month after the first parcel arrived I wrote again to say that the second parcel still hadn't arrived. She more or less called me a liar, saying that it was "rare" (ie "raro" as in strange/odd ...) that I was saying that I had received one cutting and one plant, when she remembers that she put the pots in one parcel and the cuttings in another, so as to protect the cuttings. Well ... obviously not, because I got one potted plant and one cutting in the same plastic box! She asked if I had a photo of the parcel I received, which I did, and I attached a photo to the eBay message. Maybe I should have asked her to send me a photo of the two parcels she's so sure she sent me! It's been a couple of days and she hasn't replied to my message, so I wrote to her again this morning. I'm going to wait until tomorrow, and if she still hasn't replied I'm going to get eBay to sort it out! I've bought from this seller once before, but never again! I want a refund, because I'm certainly not going to trust her to send me replacements ...

I have a post with a photo of what I received on 9 July on this blog ... titled "9 July 2019".

I can understand that things can go astray in the post, but if she's saying she's so sure she sent me two parcels I'm afraid now I don't believe she did send a second parcel.

UPDATE - 17 August 2019
I messaged her again yesterday, asking if she's received my previous message - knowing full well that she was ignoring me! She didn't reply, so this morning I opened 4 requests for refunds ... and wonders of wonders, she's issued the refunds! Never again ...
