If this is ISP-managed space ("provider aggregateable", PA, in RIPE lingo)
this is a matter between the end customer and their ISP.

If(!) the ISP has been well-behaving RIPE member and documenting their 
assignments in the RIPE DB, the historic snapshots of the inetnum 
records will shed light.  But I see this as somewhat unlikely, as it
seems the ISP is unwilling to fix up the mess they created for their
new customer.

I'd just send laywers their way - "you gave us these addresses, they
are close to unusable, go fix things or give us clean ones, or we'll
change ISPs again and you pay for all costs incurred"...
