I'm on an 18 months contract with o2 and last week I changed my unlimited Bolt-On. After using it for the last week I realised that it wasn't relly worth it and wanted to chnage it again. Gave them a phone and htey said I can't change it for another 3 months. Does anyone know of anything I can say or any legislation that would allow me to change my bolt-on early? It's extremely annoying as no-one said at the time when I changed it that I could only do this every 3 months.
