Dear Nicola:
Without actually seeing your countertop I can't venture any comment.
The issue about the uneven edge could not be contemplated by industry standards, even if there were any. As for the fissures, etc. those kinds of stones are prone to that and it's their natural characteristics. The vast majority of granite and “granites” are like that. Of course, if they are too many, then one might have a case; but, like I said, without actually seeing your stone I can't make any assessment. Sorry.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
