Hi Barleyman,
Thanks for your post and apologies to hear that you are having an issue with your new package.
Taking a look at things this end, it appears as though the SIM was set up on a chargeable tariff instead of the oomph plan. It looks as though you spoke to someone who explained this to you according to the notes left on the account. If this isn't the case I can only apologise.
We can look at getting things sorted for you here however we would need to do a web chat as we will need to go through some things, including a credit check. If you're happy to do that with us then let me know a time you are free between 10am and 3pm tomorrow so I can schedule you in.
Many thanks,
