Poor workmanship, poor after sale service

Jhb North plumbing cleared my drains twice and I had no complaints, so I recommended them to me neighbour when she had to replace the main water supply pipe to her house. The workmanship was shoddy. You don't cut a polypipe at an angle when it doesn't fit, then expect the fitting to hold. Then when the fitting \blows apart"you tell the customer all your plumbers are busy and it can only be fixed the next day. From a supposed 24 hr plumbing service"
