Enough to make anyone boycott eTolls

While I was overseas my credit card expired. The outstanding amounts were paid by EFT. Upon my return the new card details were provided. Yet no amount of calling the call centre or visiting the so-called Customer Service Stores can get the suspension lifted and the e-tag operational again. I've lost count of the number of interactions I've had with these people. My complaint case number is *** and I cannot be reached on the phone. It would be really nice if someone senior would resolve the issue and confirm it by e-mail.
