faultly goods not replaced

i bought a samsung z4 at ackermans arcadia (sancardia mall) beatrix the service was good however the phone gave me problems hards 24 hour after buying it i went back to the store a lady told me to go to menlyn to samsung to fix it on my account and she blammed it on the tizen software. i decided to buy a different phone and leave the old 1 i went and bought a samsung galaxy grand prime the phone gave me joy but my joy was short lived as i realised the phone had a faulty battery it goes from 98% to 2% literally with activity n i was told that i must take it to the groove it is clear all phones at ackerman are faulty and they dont take responsibility , how can i drive to menlyn at my own cost for their fault. i am closing my account with ackermans and advice any 1 not to buy phones from there as they will tell u there is nothing they can do since the phone belongs to mtn and or vodacom i have been a loyal account hold with ackerman but now i will close my accounts with them i wasted R2400 and i have to pay my account but there is nothing they can do but i have to pay this amount. with intereset ae people dont buy phones from ackermans vusi **********
