Incomplete job and did not honour invoice- bad att

In short, Aquarius Pool &amp; Spa invoiced me for pool, plus 3 solar panels &amp; removal of rubble, with the usual extra's. left my property without finishing the pool installation ie no electrics done,( pool ws running on an electric cord on top of the paving) left DB board in the box, NO SOLAR PANELS &amp; the rubble , about 4 skips, in the servitude behind my property. He also gt to do the extra paving job , for which he gt paid in full &amp; to date have nt received an invoice. Left the job undone, which took 2 wks too long &amp; bad workmanship all over- poor grouting, uneven,unaligned &amp; incomplete as he fell short of paving. Pitched up late with workers everyday at noon.<br> CONCLUSION: Had to pay additional costs to redo all the paving including the cement under the coping tiles around the pool, by another contractor, for an electrician to connect the pool pump &amp;light, rubble removal, backwash installation for pool, cleaning of site, repaint all the walls they dirtied, re-installation of braai cupboards they removd &amp; arrange solar panel delivery &amp;installation. Do not ever pay him in full until job done. He harrassed me for early payment too.
