Tenant Damaged Property But Property Manager Already Returned Deposit

[Jay Sing]

I recently went to my property to inspect and prep it for new tenants and found that the old tenants had let their child do some sort of project on the granite counter which left some bad ink stains in a variety of colors (very noticeable). Thinking that the cleaners would be able to wash them out, our property managers returned the tenants security deposit.  The cleaners were unsuccessful at removing the stains and the property management company is now telling us to basically suck it up.  I am not happy about this, as I feel that the tenants damaged the property and should be responsible for the cost to restore the counter to its original condition or the cost to replace the damaged areas.  Am I wrong for thinking this?
