Your /48 isn't portable, so, no, too bad. If you've got a contract which extends beyond the period where they're an LIR, maybe you have a breach and would seek compensation, but RIPE doesn't care. See also, "What do you mean the guy I leased this apartment from has sold it?".
Most IPv4 space also isn't portable. Even if you have a /24 (enough IPv4 space that it could be portable) it usually isn't, if you actually need portable space you need to make sure that's what you're actually getting, it will probably cost more.
If it's portable then you can just take it with you to another provider.
