A random £15 has been taken out of my account even after paying my bill ?

[Deceptivefuel]

I paid into my account £40.00 which is more than I'm supposed to pay monthly for my device so it was carried over but now I looked in my bank this morning and £15.00 has been taken and I don't know what for

What does your bill show it to be for?

That's the thing nothing being shown for it

If you post a picture of your bill we might be able to explain it. Don't include any personal, data like your Sky account number.

Are you sure it's regarding your Sky subscription? Could it be Sky Protect insurance operated by Domestic and General although £15 seem a bit high.
