Woodstock drilling Rustenburg

Woodstock Drilling in Rustenburg is a no go service. I requested for drilling for 30 meters which ended in 60 meters. Fair enough,no one can guarantee water.I paid for 30 meters steel casing which was unforseen. I was told the hard rock was beneath 30 meters.At 48 meters they got water but instructed them to drill 12 more meters. I was told by the guy who was in charge that the PVC was optional. Having paid more than 45k, I opted out of the PVC. Two days later when trying to sink the pump, the hole had collapsed from 34meters. Upon equiry,i was quated 33k which could have been easily avoided had the man in charge told me of the likely consequence of not using the PVC because they are subject matter experts. This cannot be our fault since they are supposedly knowing much better than any of us. I will not recommend Woodstock Drilling to any living soul and am utterly disappointed at their service. This is tantamount to ******ion and utter exploitation of the needy.
