V-Guard Industries — 1 HP pump

I buy v guard 1 HP pump from local store, in 9 to 12 mint I started facing the issues, I have rise request for repairs, when the technician came and check, even they don't know how to loosen screw and faster, they tried to fix the issues by setting marriage invitation paper in router chamber as a gasket, such very cheap things to with the motor. It's also not resolved my issue, after that they took my motor to the service center, and gave back on next day, after 5 min the same issue happened, again they put a grees and started the motor, it's now just 2 to 3 month when it repaired, now again I am facing the same problem.
