Phone is 3 Months old and freezing

To whom it may concern<br> <br> I have tried to contact the vodacom online department regarding my phone and I keep on getting put through to someone else. I have had my phone for 3 months and it is freezing constantly, I reset the phone and everything but nothing worked. I insist that this problem gets resolved as I refuse to go 3 weeks without a phone as it is still practically new!!<br> <br>
