I dont usually carry a mobile phone with me and if I did I dont see why I should have to incur extra charges in reporting these situations to them. Perhaps they should install some sort of contact system at the docking stations.
Now the good news after a few frustrating days. I have had the second amount refunded by the bank and I have been told that I will get the original charge of 150 pounds refunded. This has been authorised by Caroline Pidgeon. So emailing these people seems to have worked wonders.
