pool cover

purchased a pool cover from Sub-Saharan Tents and Tarpaulins , a day later i discovered that the pool cover has defects due to extensive plastic welding . I the called owner who had an attitude on phone tells me that its a cost for him to come and have a look at it . When cover was purchased and install the owner assured me that it comes with 2 year warranty on workmanship and product .Owner refuses to take any of my calls or reply to my texts .
