Bad Bad service. Vodacom is useless.

I received a faulty phone. Sony Xperia L. <br> I sent my phone 3 times for repairs and nothing has been fixed. <br> I am a contract client with vodacom for over 5 years now. This treatment is unreasonable. <br> My phone reboots the whole day. It cannot update apps. The phone freezes. After it reboots my phone battery goes very low. After a simple call the entire phone freezes and it has to be switched on and off to work again. <br> I will not be taking this phone for further repairs without a replacement phone that is android. I need this phone because of emails and the nature of my business. Or I will receive a new phone. <br> I left this situation far too long.
