Can anybody help - when I signed up to O2 refresh I had a 20% UNiDAYS student code, this was applied for the first month and I paid £10.86 airtime and £47.05 device plan. I have just checked my app and my device plan is still £47.05 but the airtime has gone up to £28.78? The discount was supposed to apply for the duration of my contract which is 2 years.
Thanks in advance!
