To save a bit of money, I cancelled my O2 Insure - Accidental Damage Cover which was costing me £9 extra a month on my bill.
My tariff has been a regular charge of £28.25, however since I cancelled the damage cover I can see my tariff has gone up to £33.89, a more than £5 increase!
I find this really shady by O2, and what's more - I tried to see my downgraded tariff options (currently on 100GB) and the 60GB a month option is exactly the same price! (£33.89).
This is unacceptable!
