disappointments on the way....

Don't know what I'm doing wrong. Nobody seems to want to do the job. I found it remarkable enough that at the very beginning when I didn't know how to start there were so many agencies that referred me on to the next and next one until I ended up in a circle (literally I remember ending up ringing a number and the lady said "oh, you remember we spoke some time ago?" ...!).
After the energy assessment/ heat loss calculation it went downhill:

• Garry Woods from Greentec Systems promised various times "I'm going to write you a proposal over the weekend" (why the weekend?) ... I must have rang him five times or more - no progress. Hoping for progress here has delayed me by several months.
  
• Earthcareproducts not too far from here in Ware sent stuff through, asked for my heat loss calculation but haven't come back yet
• Geothermal Heating and Cooling Systems Ltd have a phone number which nobody seems to pick up so far
• Ice Energy looks good and Rickaby could recommend them too. The guy seemed to know from the first moments over the phone exactly what the only best solution is, a visit to check would cost me £500 and when I questioned anything this particular sales guy responded very aggressively.
  

a bit frustrating ...
