Take the 3-step-check
Step 2:
Before TDR can help you need to make a formal complaint to your telecommunications company, giving them the opportunity to resolve your problem.
If you and your telecommunications company can't agree, and the dispute is deadlocked
OR
its been more than six weeks since you complained and the issue still isn't resolved
OR
you aren't happy with the solution, then TDR may be able to help.
