Alfredo Campos Lawn & Maintenance

In the beginning, a year ago the lawn service was satisfactory, however he wasn't professional because he talked too much, I could never get away as he would try to convince me that he could do more, even remove snow in the winter, etc.  About two months ago, he wanted to start being paid in advance and then would only show up twice in a month.  I called and told him I wasn't happy with the service and he told me to find someone else.  I asked him if he would come a last time, (since I had already paid him) until I would find someone else.  He still hasn't shown up and won't answer my phone calls. 
My daughter hired his services to weed a small area, cover with a weed liner and install bark.  He cut the weeds, put some plastic down and threw bark over it.  That was a month ago and weeds are growing up through the liner and out the sides.  It was poorly done.
