National Floors Direct review: Carpet installation

The carpet installation was scheduled for 9/12/2022 but the installers left after 30 minutes due to heavy rain. The carpet was then installed the following day on 9/13/2022. The quality of the installation was very different from what we witnessed at a friends house, who had referred us to this company after having her carpets done which we were present for. We have been left with an atrocious carpet. Since day one we have been asking for a reinstallation or refund and this company will not give it to us even though we’re covered by a warranty. They tell us no, we can fix it we’ll send someone out. Three times they sent someone out and they could not fix it and they still denied us a reinstallation/refund. There is a huge seam running across the center of the floor visible as soon as you enter the house but the biggest concern is the buckling everywhere so much so it’s a tripping hazard. The cost of this was $5,600. They denied us reinstallation within the warranty period. A friend of ours who works in home improvement says it seems like they did not stretch the carpet or the carpet had gotten wet from the rain the day before. The photos attached are only an example of what’s going on, our entire house looks like that.
