Welcome to Vodafone Community
I have a pay as you go SIM in a dongle for cctv, twice the balance has now been removed from It, I have not manaed to use 2gb in less than one week! I keep a close eye on the balance making sure I do not go over, the problem is the account is not in my name however my name is on the account but this means an online adviser is not helping me at all and I can never get through on the phone.
I just really need a way to sort the problem out because it was fixed before and the lady I spoke to said it would not happen again
If your listed on the Account as an authorised person then there should be no reason they cannot discuss things with you.
Perhaps pick up a new Payg SIM card and register this yourself and use that if that would help.
The myvodafone should help show where the credit has gone.
Alternatively Live Chat or Customer Services on 191 should help.
