Bunch of *******,selling inferior junk

Bought a tap this morning,fitted it and it leaked, tool it off to return it. Lo and behold they don't refund or exchange this item . Got told that I must turn off the tap. Also to fit tape ,had done all of that . On closer inspection I found that even the thread for the hose is of inferior quality. Non of the adaptors fit. Almost the same price as builders ,was just closer. Well that is the last time that shop will ever see me or my money . Typical bunch of *******
