NSE TRADING CORP

We didn't select NSE ourselves.  We placed an order for a new hot water heater with Home Depot on 11/23/2012 and NSE was either assigned or was given our order to fulfill.  The estimator from NSE (Joe Tantillo) arrived at 9:00 PM even though Home Depot told us the window was between 1:30 PM and 3:30 PM.  His explanation was that he just finished a job and hit traffic.  OK I understand that there were a lot of other people impacted by Sandy but why couldn't he have called us to let us know?  He looked at our current setup and gave us an estimate of $1000 for the new hot water heater with installation. 
A few days later, National Grid came to inspect our boiler.  They said it was dangerous to operate the boiler since the burner assembly was under water during the flooding.  National Grid shut the gas supply to the boiler.  We contacted NSE and told them we also needed a new boiler.  We had to call NSE twice to get a written estimate for the insurance company.
Home Depot called us on 11/26 for a deposit on the boiler and hot water heater which ended up costing a total of $7,953.  We asked for an installation date.  We were told by NSE that the boiler would arrive around 12/4/2012 and a boiler would be reserved for us and to call that week to schedule the installation.  When we called NSE (three times on 12/3), we learned our boiler wasn't in stock.  Either it didn't come in or it was given to another installer.  The bottom line was delivery and installation of the boiler and hot water heater was now pushed back to 12/14. On 12/12 Home Depot called to say that the 12/14 date was now 12/15.
It has been an extremely frustrating experience.  We didn't know whether to call Home Depot or NSE about delivery and installation information.  I don't think we will use a big box store again for installation without nailing down whom to call.
