Malcom, serena and text message speech stopped working

Hello,

Done updates to the satnav Malcolm's voice Serena's voice and text message to speech no longer works I have emailed Tom Tom who have told me to do a soft reset which i have done, a hard factory reset, I have deleted the voices off the sat nav I've deleted text to speech off the sat nav but can no longer find how to reinstall it I have reinstalled Malcolm and Serena's voices back to the satnav I can select them but they do not work and it's really annoying as I can't read my texts while driving because the voice is not working. I am going to return the satnav to halfords or more likely going to throw it through a window. Tomtom take ages to email back.
