NO RESPONSE FROM PEOPLE AT SAMSUNG

handed in my Samsung TAB at Constantia repair centre and i was advised by Refilwe Mahlangu that the system board needs to be fixed. i sent her a few mail advising her that the phone is on contract with mtn and that i should not be paying for the repairs. She reads my e-mails but does not ever respond to me to advise what the next step. i even tried calling them but the phone rings on for ever with no answer.<br> <br> this is not the service i expected to receive from samsung and i am really disappointed
