I've just checked my ee account and had a charge for £3. Not much I know but for a one second call to my voice mail, it's a bit excessive. apparently if you reject a call which I did (from an unknown number) it automatically gets re routed back to your voice mail in UK, and charges you twice, £1.50 for call and £1.50 for voice mail. EE have refused to refund me, so I have asked for it to be escalated. Its the principal now. Just checked a previous bill, and I had charges on that as well. Phoned them back and they eventually agreed to meet me half way and I got £10.50 back. I've now switched off my voice mail permanently.
