Faulty car hands free unit.

<p>A &nbsp;faulty system ( The technician himself told me that)was installed and when I asked for it to be rectified 4 months after installation the company &nbsp;said I must pay again. After 2 weeks of me chasing them and Hyundai whom I bought the car from &amp; who suggested Designer Audio do the car hands free kit , I eventually had the system fixed by designer Audio but only because I kept chasing them, harrasing them &amp; losing my temper.</p>
