Arena Group's poor service

Arena Group installed my borehole pump. I pumped once and thereafter the pipe and pump came loose from the connector at the top of the pump and was sitting about 1m below the surface. I called Arena to try to recover my pump and they succeeded in droping the whole installation about 5m further down the borehole. I managed to eventually find a company that was able to recover the pump. I claimed and send a letter of demand via a lawyer for the cost of recovering the pump and the interim plans I had to make (this took about 3months) to water my orchards of new Macadamia trees. Arena Group, after at first agreeing to settle the claim, backtracked and denied all culpability and refused to settle my claim. I had two independant companies inspect the failed installation and provide me with a report. Both reports clearly lay the culpability at Arena Group's door. I tried on many occasions to talk to Jimmy Farnham, the MD/Director , and he refused to return or take any of my calls and when I visited their offices, I was told he was in, but was directed to another person. As I exited the building, I saw him leaving in his car. If it were possible I would give Arena Group a negative star rating for not only there poor handling of the situation but also for backtracking on their word. There after sales services is poor beyond belief and I should you need any pumps, solar, generators or any of their other products, I suggest strongly that you look elsewhere.
