All talk no action

A while ago i lodged a dispute regarding 2 transactions on my check card. I reported previously that the call centre shoves you from pillar to post in this regard, shortly after placing the complaint on helloPeter that did contact me assuring me that that will resolve the issue and that I needed to complete forms. I have since not recieved any feedback and once again being shunted from one department to the next I have spent a considerable amount of money on airtime trying to no avail to resolve the issue. Nothing has happened so far they talk but do not produce results.
