April bill error?

[#1]

Hello Just received my April bill but am being charged for 100 mobile minutes when I have reverted back to unlimited calls which includes mobiles. I assume I am paying in advance for this month's calls (£9) so why the extra £3?

@goosehead Hey! I've raised a billing task for you because that shouldn't be on your account and updated you further on your account here.
