Worst buy ever

This star rating should have minus stars, this one star I rated is not my true rating as I have to click it to air my view. I had this company put up a veggie tunnel on my plot June 2019. The workmanship is non existent and so is the after sale service. This company did not give any documentation, when I delayed my final payment I was threatened. This company said they will replace the plastic as it is being ripped by the bad workmanship, still waiting from June 2019.
