When I went sim free in 2013 I was told that my bill would be £17 pm with a discount of £10, £7 pm was acceptable. In 2015 this increased to £18.50 pm with the same discount, again acceptable. it has just increased again to £21.50 pm with the same discount. WHY????
In real terms, that's an increase of 50% in less than two years. CAN ANYONE TELL ME WHY?
