It only took these guys not even a week to fix it at no cost as it still falls under warranty and honestly, I was expecting it to take the whole long month to be fixed but they did an explendid job so quick.</p> <p style="margin-top: 0px; margin-bottom: 0px; color: #666666; font-size: 11px; line-height: 20px; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; background-color: #ffffff;"> </p> <p style="margin-top: 0px; margin-bottom: 0px; color: #666666; font-size: 11px; line-height: 20px; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; background-color: #ffffff;">Phew my warranty helped a lot.</p> <p style="margin-top: 0px; margin-bottom: 0px; color: #666666; font-size: 11px; line-height: 20px; font-family: 'Source Sans Pro', Verdana, Geneva, sans-serif; background-color: #ffffff;">Thanks Sony and MTN for such a quick fix.</p>
