At least they cared. I found an enumeration attack on an Australian referral service where phone numbers were keys and it returned way too much personal information. Responsibly disclosed numerous times, LinkedIn contacted employees. Not even acknowledged and at last check, still open vulnerability.
The sad thing is, that at some point they truly get exposed (big leak) and your name might come up because they have nobody else to blame. I wish you the best and hope you have lawyer insurance.
