defy 3 plate is faulty

My name is ntanganedzeni my husband bought a 3 plate defy stove on the 06th march 2015 on instalment, i called the store to report it being faulty 3 days after i talked to Mr Malelu who transferred me to compain department were i was assisted by Leticia who promised to send people to come n collect it. Days went by and i contacted every working day through the phone all i 2as getting was promises from Leticia that she will get back to me. On the 31 i went straight to the store to complain i was promised the same thing that she will send people to come and look at the stove. I called again on a daily basis to get her attention she then promised that on the 16415 defy people will come, i took a day off at work and awaited for them but they didn't come. I called her again 4 times on the 17415 and she promised on all calls to find out what happened to defy people and she will call me back but she didn't come back to me. I don't want a repair because i reported it before 7 days guarantee was due.<br> <br> Regards<br> Ntanganedzeni<br> ***<br> ***
