I mean concerning them, who play still. Not so much to do if they stop playing

Examples from my own situation:
The agreements with Suppliers have functioned OK (but there I'm the buyer, and I suppouse most ones want to sell if playing Kapilands

but concerning buyers - out of 5 agreements,
/3 functions good,
but
/one never bought at all, although I delivered within some hours from he told his corect company name (discussion started in forum) "because he didn't need it anymore"!!
/and one bought to start with, but have stoped buying, although he have been loged in the days after he stoped buying (agreement was DAILY delivering from me, and then I expect - almost - daily buying from him
