Well Point does not work, no water

He was a little cheaper than others so went with him.(R1500 per hole, plus callout). He dropped 2 holes for the well point. It worked fine for 2 days, and then got gradually worse (less water flow). I kept him informed everyday how it was doing, initially he gave some advice, but eventually just said "I have water, so don't contact him again" and then blocked me. 2 weeks after install, there is no water at all. I contacted him on the 2nd number, I emailed him, I contacted him from a number that was not blocked. No response. All I want is the well point to work or my money back, but he will not reply.
