Modern Edge Landscaping & Services

Matt did my deck & landscaping 18months ago.i paid him promptly.my friend is a witness to this.now many nails popping up creating a trip hazard.i rang him & left at least 3 messages,even wrote a personal note thru his wife to get back to me BUT NO REPLY! I am very disappointed.no courtesy to reply. I hv a few questions..such as did he use twist lock nails,is this usual occurrence??so I would not recommend him at all.
