Recover money for damage done to stone wall by dumpster company

[Timothy Peck]

Hoping to get advice....I am renovating a SFR in NY and had a dumpster delivered. The contractor ordered the dumpster from a broker company and was there when the dumpster was delivered. The driver knocked the dumpster into a blue stone wall which lines the driveway causing significant damage. When I called the dumpster company to ask for them to fix the issue or to compensate me for the cost to do so they seemed accommodating at first and asked me to send pictures of the damage and to get an estimate. I sent pictures and the contractor provided me an estimate of $2400 to repair the wall which I sent along to the dumpster company.

At that point they said that they thought the estimate was high and that they needed to talk with the contractor.  Apparently there was an argument at that point and then they came back to me and said to deal with the Broker company who we ordered the dumpster from.  As you may have guessed, the broker company said that they were not liable in any way but they would work with us to "mediate" a resolution with the dumpster company.  Back and forth, back and forth and eventually the dumpster company stops communicating and ignores all phone calls and emails.  I threaten to leave bad reviews on yelp, etc. if they do not respond and then they do respond only to tell me that they have no liability in the issue and that there is "inherent risk" in ordering dumpsters and I should have been aware of this.  

At this point I'm not sure where to go with it.  Is it worth hiring a lawyer to try to recover $2400?  Any other suggestions will be much appreciated.
