Hi, from 30 March 2017 your monthly price plan will increase by 2.5% in line with the Retail Price Index (RPI) published in January 2017 and as detailed in your terms. For example, a £45.56 price plan will increase by £1.13 a month. Please visit http://discover.ee.co.uk/rpi/8IZ9gh
for more info and to calculate your new monthly plan cost.
I presume this increases is to low to cancel without having to pay remaining contact?
