Worst battery place ever

Battery centre was taken over by exponential batteries in Mafikeng bought a battery there not even 2 years ago battery dies ... Took it to them tested it said there is nothing wrong ... Drove one night with a six month old baby got stranded at the side of the road.... Took it back again nothing wrong with the battery according to them .... But with no acid so how did they test it ... They are not even worth a star ... Place is dirty
