Best choice landscaping corp. and nursery, Miami FL

We hired this company to do our landscaping twice a month over a year ago. They did a very good job at the beginning then slowly their work deteriorated. About 2 months ago (Jesus) told us he would kill the weeds that we had in our lawn and sprayed some chemicals, one week later our entire lawn was dead except for the weeds. We have a fairly large yard and it looks like someone torched it. When I asked Jesus what was he going to do about it he said it was our fault, not enough water. We water our lawn every day and it had been raining. No solution was offered to fix the damage. We now have a yard full of weeds and no grass. My husband fired the company. Do not hire them, they are not reliable.
