MSB Group Construction

I hired Clifton Mew's dba. MSB group construction llc to install 93x70 white vinyl fence with 2 gates. Contractor to buy all materials and remove all trash
Also hired to install 15x18 concrete slab also to buy all material and remove all trash.
Clifton started job to install fence and then stated fence quote was not enough to cover type of fence I wanted. His workers started to install wood posts. All woods posts were not installed properly (little to no concrete, not spaced equally for fence panels) after weeks of asking for fence to be completed Clifton would give numerous excuses for delay. I requested full refund for fence deposit of $1250 and $900 for concrete slab (nothing was ever started for concrete slab)
Clifton has refused to contact me or respond to text and email requests for refund.
His workers left numerous bags of concrete out in the elements which hardened with rain. He is not professional and not honest with his work.
