Sports relief #bishopshell text number - donation not taken!?

[#1]

Radio 1 have been running a donation campaign for John Bishops week of hell (#bishopshell) to raise funds for Sports Relief.

I texted the donation number, supposed to donate £1 per text but I have just been charged a small amount for the text, the donation hasn't been taken. I definitely had the funds as I topped up specifically.

Do these donation numbers not work on GiffGaff?

They normally do, when did you do it? Give it a few minutes or maybe a half hour to do it.

Oh ok, it was about half an hour ago. I just assumed the donation would leave account at same time as text payment. I'll check again later and see if it's gone.

Thanks!

Was it to 70011 ? It seems the reverse billing isn't supported by giffgaff

Just been billed 45 minutes later so the reverse billing is supported
Very unusual to wait that long though
