Poor Service Delivery

I installed a Penguin Pool during 2004 which was a nightmare. During January 2015 I was forced to engage with the company again due to a hole in my pool (life time guarantee) - cause - poor workmanship as per inspector. It was a mission to get them to my house to inspect the damage - 2 weeks. They finally came and fixed the pool. Now I'm stuck with a fixed pool with different colours (new repairs vs. chemical damage). I was informed by the contractor that it will blend in over time. Not happy with this I requested them to \grind and flow coat"the pool to get a better finishing which will cost me R8500. Their sales staff was extremely sufficient and concluded the deal in 1 hour and also received payment. It has been two weeks since I requested the work to be done and I have a half recoated pool and dead lawn where the chemicals were spilled onto it. They started on Monday 23rd and it's the 27th still without a pool. Tried to contact the owner Mr Du Plessis on several occasions and left message as he is enormously busy and was each time passed to one of his *********** staff that \""over promise and under deliver\"". I hope that my problem will be resolved before winter"""
