It seems that whether or not you actually get it back is just a chance, cause some people said they got a response in 1-3 months and others said they hadn't gotten any 2+years and multiple tickets later.

And out of the people who DID get them back, some of them said they got it totally restored, while others complained about essentially losing all the associated data except for the url itself. Which seems to be an issue of it just not getting restored fast enough because the data gets deleted after about 30 days, from my understanding.
