website information poor

The unit is fine but the ordering/delivery/installation information is really poor. I paid for delivery I shouldn't have had to pay for. I was not informed that the unit wouldn't be installed when it was delivered and had to wait for a contactor to show up. The installation fee is more than I paid for the heater itself. I really don't think I'll be doing further business with Lowes or their contactor.
