LeafFilter review: Did not complete work

Leaf Filter salesperson came at my request for an estimate on gutter guards on my townhome. After inspection of my current gutters a proposal was made that included fixing the pitch of my gutters and adding 2 elbow connections that would help with flow as well as adding a downspout to the back gutter to address the overflow. Installation happened 2 days later. Installer indicated he was not told about new elbow connections or adding the new downspout and did not have the necessary parts to complete those components. I called the salesman who initially indicated that I misunderstood and he did not say a new downspout would be added. I did completely understand and could repeat to him the logic he gave me for why it was necessary. I then called the business office where I was told I would have a downspout. Salesman called back and said sorry for the misunderstanding and i would get the downspout. No repairs have happened even though I've contacted N.B. again. No communication. I'm still waiting for repair.
