Good Morning Wayne, don't talk to them, but sit down and write a properly descriptive letter of your situation and action so far taken and ensure it is all properly signed and dated with your full contact information.

Ensure all contact is in writing, and refer to any phone contacts you make with time and date in other written material and record the person's name and work area.
I suspect you will otherwise get the brush-off!

Having a "paper-trail" creates a powerful argument after a period with indisputable evidence of the problem history and they have a responsibility to answer any written material also in writing, if your letters are answered by a phone call, request a written reply also.
In dis-satisfaction cases "the pen is significantly greater than the sword".

Cheers, qldit.
