Jay Jay Plumbers - an insult to the work of plumbing

Most probably a fly by night company in existence to grab some jobs from insurances. One of the most despicable services received. Arrogant and stoopid! After their bellow low level job, I contacted them for sorting out the garbage work they left as signature of their value. One cretin said that he'll send "his team" - probably in the afterworld. So now I shall take up with the insurance. Why does the Nedbank insurance, use such low quality service providers?
