Genesis Hydrovac

I purchased a Genesis Hydro Vac a few years ago, recently the machine has been leaking when the water function is operational. I took the machine back to Makro as it was still under warranty, this was on the 7th February 2018. Around the 3rd March 2018, I received notification that the unit was fixed and ready for collection which I did. When we used the machine after it was returned from repairs the problem was worst then when we sent it in. Shocked that the product goes in for 6 to 8 weeks and comes back like it was never fixed.
