There is nothing that you can do to fix the problem, you will need to contact technical support and have them book another engineer for you.
All the information that the person you speak to will need is in the "bluetools report" so if they are not sure then ask them to check that, or consult a level 2 for further advice if they are still stuck
Any relevant information from this report can be passed to the engineers when the fault is booked in so the engineer should be able to fix it. As for how to fix the problem, i honestly have no idea... i am here to diagnose connectivity issues... i leave the fixing to the engineers
