IPool Sears, Hayward Pool supply Bought pool heater from Sears and could not return it due to fraudulent advertising , Internet

I purchased a pool heater so my Granddaughter could use our above ground pool longer from Sears because I thought they would be a more reputable company.    When it arrived there were no instructions so I called Sears and was told they could not help me since the heater really came from Ipools.  I called Ipools and they told me they could not help me and for me to get the instructions off of the Web at Hayward Pool Supplies.  I got the instructions and found out this heater did not run off of a small propane tank, instead it used a 200 lb propane tank  that ended up costing me over $800 to get filled and installed.  I then had to have an electrician put in a line since the county would not okay the existing line to the heater and pool, costing another $900.  I was told by Ipool and Sears that they would not accept returns on this item and consider that I was ripped off by Sears for misrepresenting the product and deceiving me into thinking I was getting this from them; Ipools because this product was misrepresented and Hayward because it is a poor product.   Do not buy off line from Sears or Ipools or you will get ripped off.
