JM Environmental services disappearing before the work is done, after all money paid

Pathetic service from Jonathan, the owner of JM environmental services. Also trading as Bosveld Tree Fellers. I contracted him to fell and remove several large trees. He insisted on payment up front, before all the work was done. Then he disappeared and left me with a huge pile of tree branches, forcing me to pay other contractors to complete the work. Also issues with the wrong tree being removed.
