After purchase silent seller with form disabled

Hi,
On April 22nd I bought a LP record from a seller (don’t know if I’m allowed to name this seller…)
But no news from him since my purchase and the seller’s form appears disabled.
What can we do when this kind of problem happens ?
What Discogs does when this happens ?

Any communication about a sale should be on the order page. I don't think a seller can disable that. A link will appear after four days, for a seller not responding.

You may try ing Discogs customer service: they respond promptly in 4-9 weeks.
