Why is £2 being taken off my balance each time I top up?

Every time I tip up, no matter what amount £2 is taken off my balance, I have no active bolts Ons or extras, I buy them SS and when needed with my credit but this is stopping me and it’s been going on for 6 months now

It could be a premium rate service that you aren't aware of

But you'll need to call customer service to check on 4445.

This happens to me every month too, they end your package at midnight then don't apply your new package till later the next day (When you get the text) The 2 Pounds charge is for the internet usage, even if it's just a tiny amount. Phone CS and complain. I did last month and got the 2 Pounds refunded, but it's outrageous, think how much money they are making from this.
