J's Seamless Gutters and Downspouts

From the start, communication was very difficult.  I received an email
letting me know the work would be done by a subcontractor since they had
sold so many deals, and was given a number to call.  The subcontractor
was difficult to reach. 
After several attempts, we received an
estimate.  The estimate was a crude drawing on a notepad with no
measurements or details except for the price.  However, when trying to
get the work scheduled, it took 2 and a half months before any work was
done.  I contacted the primary contractor a couple of times, and found
them to always be kind.  However, they were hoping the subcontractor
would step up and address my concerns.  Eventually, 55 feet of gutter
was replaced along with one downspout.  Other work in the estimate was
not performed.  I attempted to resolve this with the subcontractor, but
he kept insisting that any additional work would cost me more money than
I had already paid.  They did come out and add a 1.5 foot section that
they had overlooked, so I now have 56.5 feet of new gutter, but I should
have had enough with the coupon value to do much more.  J's Seamless
Gutters and Downspouts invoiced me for 77 feet of new gutter down one
side of my house when my house is only 56.5 feet long!  And did I
mention the seam in my new "seamless" gutter?  I asked the subcontractor
why the seam was there, and was told he would have to check with the
guy who actually did the installation and get back to me!  Too much
drama for a "Big Deal" that should have been a simple job.  I invite any
disbelievers to come by and see seam in the seamless gutters and
measure the length of the new installation.  I measured twice just to be
sure myself.
