When Companies Attack ...

I never thought that I would be in a situation such as this.  Over a year ago, I reviewed a salon visit and the review was negative as I honestly had one of the worst services ever.  Since publishing that review, I have gotten nasty anonymous comments.  I published one and responded, but never got a response back.  Then just tonight, I got a racist comment awaiting me when I came home.
Does this sound like a disgruntled employee? Who else would care so much as to attack me in this manner?  Most companies value their reputation and usually want to make right when a customer is unhappy with their services.  But somehow, I'm getting these very angry and personal attacks.
I am not sorry to have written my review as they had no respect for me when I was a customer, and they continue to attack me years later.
I don't want to jump the gun and say it is the actual owner of the salon nor it's members, but the comments seem invested into that business to defend them with such vigor.
Racist attacks will not be tolerated. So I am publicly logging this on my blog for everyone to see.  If this harassment continues, I will be seeing a solicitor and the police.
Here is the blog post which I updated so you can all see what sort of response I received from this company and/or someone who is defending this company.
