Poor service and workmanship on pool

Since August 2015, after I moved to my new residence, I have experienced problems with my pool. I had bought it from an elderly lady that had not maintained it well. When I moved to my new residence, I noticed that the level of the pool water dropped down to the weir within two days after the pool had been topped up. I reported the matter to the estate agent I bought the house through and it was brought to the attention of the previous owner who had signed a declaration that the pool was in perfect working order. After liaising via attorneys, she finally agreed to pay R10 000 towards having it fixed. I was referred to "Pierre's Pools' by the owner of Aqua Dazzle Pools on the East Rand. Dealing with Pierre is like pulling hen's teeth. He promises to come and doesn't turn up. It took a good two weeks for him to meet with me. He quoted me and then some weeks later started removing the fibre-glass lining. It looked very nice once the gelcoat was finished but I soon discovered that there were sharp fibre-glass ridges in the pool and he said he would return to fix them. All in all, my pool has been emptied four times which is a tremendous waste of water and occurred during the period when water was scarce so had to get permission from the local municipality to refill the pool each time. I asked him to build an extra step in the shallow end so I could get in and out of the pool easier - I have a back problem. He did so. I approached him when building it because the square was made out of bricks but the centre was just sand. I asked him why he wasn't using concrete in the middle and he said it wasn't necessary. The step is now dipping when you stand on it, particularly in the middle. His worker did not clean the paintbrush properly after painting the pool and the mosaic pattern was laid and painted over - or I should rather say SMUDGED over. There are white marks in numerous places on the mosaic - it looks shocking!!! In short, the pool gelcoat/paint has delaminated three times i.e. is peeling off and being sucked up into the weir by the pool cleaner. Pierre sent his worker to fix it three times and, when done for the third time, I paid for and supplied the gelcoat/paint, brushes, turpentine, etc which cost me R1 095 because he said he didn't have the funds. I have now asked him to return to fix it a fourth time. I sent Pierre a WhatsApp message and e-mail on Friday 6th October asking him to contact me over the weekend. He has not contacted me, which is no surprise. To make things worse, I have discovered a leak in the fibre-glass at the top step of the pool so my pool is leaking water yet again. As you can understand, I am extremely frustrated. I did expect good workmanship and neither the service nor the workmanship met the average requirements let alone that of excellence. I warned him that I was going to take the matter further so have submitted the information to Hello Peter in the hope that it may assist me in getting this matter sorted out once and for all. This matter has been outstanding since 2015!!!
