Poor Quality Products

Good Day

I bought this unit (Voyager MII) 3-4 months ago at Builders Warehouse in Somerset West.

The unit is working fine,but now the bump strip is broken already,as it kept bumping against the stairs in the pool. I thought this is what its suppose to do? How can this break so soon already? Now my water quality is deteriorating as the unit is not working correctly.

What am I suppose to do now? I've just spent money buying a new unit, and I see on the box there is a 3 year warranty.

I've attached some pics to **********
