Anybody else get this email from Malev?

"If you already hold a premium frequent flyer card with any airline and you would like to swap your existing Duna Club membership card for a higher tier card, all you have to do is send us a copy of your existing premium tier loyalty card plus the documents (air tickets, boarding cards) related to all Malév scheduled flights you have taken in the past three months, and we will raise your Duna Card tier to that of your existing card.
Please send the abovementioned documents to the following:

In my case (BA Silver and Malev Blue) This would seem to be an offer to raise my Malev card to the next tier, Silver, which is below my Oneworld silver which I add all my Malev flights to. So I for one cannot see the benefit to me here, or am I missing something? Optimistically I could read this that they will offer me a Malev card one tier above my current BA silver level...

FYI 90% of my flights are on Malev metal but I changed to BAEC, and let Duna club drop from Silver to blue, as c.50% of Malev points were never posted, the points expire after 3 years, and probably the main reason, I asked for clarification on this from them when I recieved the email 1 week ago and have heard...nothing.
