Repair on TomTom Spark C+M

I bought a TomTom Spark Sports watch on the 1/3/16...after 2 weeks it started acting up.. freezing when you try to switch between sport modes. i took it in on the 18/3/16 to get it exchange, just to be told that its not possible, and it needs to get sent away to TOMTOM and that it will take up to 3 weeks! You can imagine my disappointment, since i paid alot of money for this device!<br> <br> today is the 10/4/16, i phoned for a update last week for and been told i was only collected on 7/4/16. How much longer must i wait?? i refuse to wait any longer!! and i fail to see why i as a account holder must get inconvenienced!.<br> <br> I want the device replaced now or a refund!.
