I think I just have to give it a go at the CTTT for the princely sum of $78 without OFT mediation which I think would be a waste of time and another $78.
Have a look at KiwiPaul’s posting below. If you initiate an action at the CTTT and choose not to follow the prescribed procedure (mediation) you won’t get past square one. This issue may seem “cut and dried” to you and if that’s the case then the matter can be resolved at mediation with agreement on a binding resolution. But if the other party feels they have a valid case, the money you are wasting is the cost of making an application for mediation without going through the proper channels.
