DEATH TRAP items sold,the putrid customer service is free though

a few months back I purchased a gas hob which I recently had fitted. it costed me R1450 to have it installed to receive a compliance certificate. after fitment ,the installer nearly had his face burnt away due to a mini explosion due to a gas leak inside the unit.He informed us to contact builders,hoping they would send out a technician at their own expense. after contacting someone at the store(Kenilworth) I was told they would refund or replace. I wanted a new unit,but there was no stock and I had to ASK staff to check for stock at other nearby branches.another fail on their side. I was issued a coupon and went to tokai branch.More ******* service awaited me. Didn't see the gas hob in the isle where I last saw it at other branch and inquired at the help desk.i was told they don't sell those units.Then the lady at the help(less) desk called for assistance over intercom more than FIVE TIMES,and nobody came.i took out my slip and asked to check the code of item.then she told me in which department to find it.(after being told it isn't stocked). It costed me another R250 to have the installer come out again to fit a faulty product BUILDERS WAREHOUSE provided, that is beside the extra fuel I had to give out to get the item at another branch.Needless to say I won't be supporting this store again,nor any store associated with them
