Scammed by Dormaster/Promaster

I'll start with a few mea culpas:

• If I had done minimal research, I would have found the dismal BBB ratings, and allegations of fraud (by rival companies, but a warning sign nonetheless).
• I was naive enough to believe it was an honest mistake and that the company would address my complaints. Now I know that the correct response when presented with a questionable bill is to tell the dude to GTFO and let them try to come after you.
• I didn't request a written estimate, which BMO MasterCard says might have made them willing to reverse the charges in spite of my stupidly signing the bill.

That being said, this is what the Dormaster experience is like:

• You will be given flat out lies about part prices in your phone estimate.
• Parts that will almost certainly be required for your job will not be included in the estimate.
• The technician (shout out to my man Alan in Burnaby!) will take it upon himself to do an extra $60 tune-up that, in his own words, consisted of tightening some screws.
• When you call to complain they will tell you (each time) to expect a call back - it won't come.

One thing I'm still uncertain on is how much blame lies with the technicians (who all appear to be independent contractors) and the dispatchers.

Oh well. Lesson learned. I might not get any money back, but at least I have the satisfaction of throwing another complaint on the BBB pile, and badmouthing them here.

At least I don't have any complaints about the quality of the work.

Update:

As of Sept. 13, 2011 I have agreed to close the BBB complaint in exchange for $20.  Which is a far better outcome than I expected although I will still never use Dormaster services again.

I was surprised to see how many false claims Dormaster made in their response via the BBB; is it likely I would somehow be fooled and be more likely to accept their counteroffer?  Personally, the lies made me more inclined to fight, but rationality won out.  Or perhaps the claims are just an opening gambit in gaming the BBB dispute process, should I have rejected the offer...
