From Repair to Despair

So once again i am writing to Vodacom with a great deal of disappointment.<br> <br> After sending my phone in for a SCREEN REPLACEMENT on 10 December 2015 and only receiving it back 22 January 2016 I was shocked with the level of service delivery received from Vodacom.<br> <br> It was then after collecting my phone, checking all screen functionality on the phone in store as this is why it was sent in, and found when I got home when receiving a call that the microphone on my phone was not working as it should.<br> <br> For some strange reason it works perfectly when I put the phone on speaker however when talking to someone in the traditional way(phone against the ear) the other person cannot hear me at all.<br> <br> Two questions to Vodacom repairs...<br> <br> 1.How does my phone go in for a screen replacement, disappears for more than a month and then comes back with a mic that does not work???<br> <br> 2.Am I going to wait more than a month for Vodacom to repair this problem that was not there before???<br> <br> I previously asked that someone senior call me and I got a call from someone asking me what my problem is, please read my complaint above.<br> <br> Can I please get a call from a SENIOR person to resolve this issue???
