The change over to the new tariff was reasonably simple and quick, although I recall that the first attempt did not work and I had to follow this up to resolve. That said, as a customer for over 4 years, I was disappointed that I had not been advised of nor offered new tariffs that are available to your new customers. Effectively I have been paying the same amount as they would for half the data. This is in spite of the fact that I had been approaching and in some cases exceeding the data limits each month. To be honest, I would have thought that as I pay you just short of £100 a month, that you would be doing a little more to retain my custom - a promotional email at the least?
