Xkp804 pool pump

Good day. I bought a xkp804 pool pump on the 2019-08-08 from obaro branch in mokopane. And it worked for a month, and then it lost pressure. Then Gerhardes assistant manager replaced it with a new one for me, and now another month past and the new pump lost pressure again. I'm not really happy with this pump, but the salesman Jan at obaro told me its the best pump to buy. But after 2 pumps i dont think its wort anything for me. So can i please get some assistance from u guys, because obaro sales man Jan dont want to assist me again. He said he can't replace it again. And i can't wait for a pump to go out for repairs, and then it comes back and only last for another month. Who is going to pay my cleaning middle and time on the pool standing with out a pump. Can u guys please assist me.
