Paving nightmare

Just a heads up to anyone looking to do some paving or some alterations and want to make use of Corrie from CK Construction Gauteng, he is an unreliable lying crook. I requested a quote for around 30m² paving, 15m coping and 15m² driveway to be done, he sent me the quote I have asked him if he can split it into tow separate quotes being one for the pool area and the other one for the driveway for my budget is very tight, he told me that if he does it the price will be much more because he done it in a combo deal, he's T's and C's was that if I except it that I must pay a 80% deposit soonest witch I did. Accordingly to him it will only be a 2day job in total after I told him when I will be marbliting the pool by then the paving must be completed for not to mess any dust and debris in the pool, and then the balance (20%) payable on completion of the paving part, well now that's where the problems started, he's workers pitched up at 12o'clock 2days prior to my discussed dates of marblite please take note none of the materials was on site he pitched up 30min later with the pool areas paving only, No river sand, no cement nothing where by then his workers was taking lunchtime after they had their lunch they started to work using my materials witch he would credit me for using, 30min later it started to rain for a total of 15min by then when I looked again they have loaded there bakkie and gone were they after battling to get hold of anyone the excuse was it was to wet to work when after 20min the ground was dry. The next day no one pitched and they decided that it was still too wet to work after I told him it's dry and that is just the point of all lying laim excuses. Then all of a sudden he is helping me out because they are actually closed already, and he will complete the driveway in the new year only when I make a payment again "because the pool area is complete" now that I tel him his T's and C's saying after completion of the job I need to pay the balance now he refuses to complete the driveway until I pay him, he also refuses to credit me for all my materials he had used. Please let me know if anyone needs his number just to make sure you don't get taken for a rid like I have been. Wishing you all a happy and good year
