Kent RO — worst ever service network of Kent water purifier

I have purchased Kent supreme Mineral RO purifier online from eBay Website. Serial Number KR[protected] Installation has been done by Aqua World service provider (Address: shop no8, A wing, KPCT Mall, Fatima nagat, pune) dated on 8/05/2015. Installation has not been done properly from Aqua World Service provider. From the day of installation, I have been facing many issues like water leakage, pipe broken etc. Service provided by Aqua World in very poor and pathetic. Each time I called Aqua word service provider, there were no quick, prompt response from them. I have to call them 2-3 times for resolving issue, it has been a very bad experience with this Aqua World service provider. I don’t understand what type of after sales service does Kent provide After so many follow up, Aqua World service provider technician visited at our place, fixes issue temporarily and after 1- 2 weeks same issue occured again. Aqua world technician is not enough skillful to fix that issue, also there is no quick action taken by Aqua world to resolve the issue. I raised same issue on saturday 23 rd May 2015, but till today there representative has not visited our place. I fed up of this Kent machine as well as service provider. It was our biggest blunder to purchase Kent supreme Mineral RO purifier system. I am facing the worst ever service network of Kent. Also, I want to change my service Provider from Aqua World to Oasis Globle Enterprise located near to my home at Kaspte wasti, Chhatrapati chowk wakad pune. I have good experience of Oasis Globle Enterprise
