If I am able to stay with Idnet (just dont know at the moment) what forms of payment do thy take if you dont have any debit/credit cards ? I dont want go in to details here but I might have to make do with out any for a few months.
I know you can request to make payment by standing order. Why don't you phone support, explain the situation and discuss your options?
As Lance says, Bill, currently you can pay by standing order, but also (little publicised) by bank transfer if you do online banking.
You can also pay by cheque in advance. Contact CS I'm sure they will be able to accomodate you.
