Yes, it was good when we (means all ISP) had many IPv4 addresses.

In several month PI space will be unavailable and for more efficient using IPv4
big ISP will allow use PA space for using to smaller ISP.

It is not problem. Each customer has contract and on termination the contract all
Assigned PA space client return back.

Well, the point of "PA" is the "A" for "Aggregation".  It can be announced
(as a hole) from their own AS, but MUST NOT be taken away from the original
provider.  If the customer terminates the contract with the ISP who has
been allocated the PA block from RIPE, the PA space MUST be returned.

Just because it (sometimes) works technically doesn't mean it's intended
to be used that way, or will not cause major problems later on - as you
have discovered.
