Got the same email today, I went onto online chat and they said if I renewed (did the same last year mid contract) they would keep the price the same, I currently pay £28.99 + £1.75 for caller display, the increase was £2.50 so would have made the total for September £33.24 then from October caller display would be free bringing it down to £31.49, in the end I just agreed to renew at £28.99 (for another 18 months) inc caller display and free weekend calls (not that I use the housephone). If and when I get the email next year i'll just do the same, i'm quite happy with bt, I get 75mb down and 19mb up and the use of the bt hotspots when out and about (mainly for son)
