Lack of response from Vodacom to a post loaded 16 November 2017

I long for the day I can write a post to commend Vodacom on good or even average service delivery. Well today is not that day. After the issue with my sim card and sim swop I thought my problems with bad service from Vodacom are finally over, well guess I was wrong. I started experiencing problems with the device I got on contract from Vodacom and have been calling since Monday 13, November 2017 for assistance and have once again been sent back and forth, promised I would be called back and that this issue will be handled. It is Thursday 16 November and well nothing. The device is faulty, it drops calls, when sending a voicenote it records nothing and when receiving or making calls the person on the other side can not hear me. I am now told because I am out of my 14 day after delivery period they need to repair the phone, well I could not use the phone for almost two weeks after delivery as you did not deliver a sim card and the sim swop was not active. Yes, it is out of the 14 day window after delivery but If I did not have the sim card and sim swop issue I would have picked up the phone is faulty. I refuse to wait for weeks until this phone is repaired and want my current device replaced. Looking to hear from Vodacom
