upgrade to new samsung A5.in for repairs 3rd time

I upgraded my vodacom cell account in April 2015 from my BlackBerry to the Samsung Galaxy A5. In October 2015 the phone just stopped working. I sent it in for repairs at Vodacom Heidelberg Gauteng. after about a month it came back still not working. I sent it in again for repairs through the same vodacom branch as it is still under warranty. <br> <br> It came back but this time they damaged the earphone plug in or speakers while repairing the screen and software problem. so I had to send it in for a third time. I asked for a nes phone but it seems you get no clarity on that issue. <br> <br> its annoying to pay for a product you have not used for about 3 months especially when its not your fault.<br> <br> my phone is currently at vodacom sandton again for repairs. seems my Samsung A5 is a faulty phone but yet they wont offer me a new one<br> <br> I am so annoyed...<br> <br>
