I have been trying to connect through Lebara for a few weeks (it was working before then), but just get a "no service" message on my phone. My account on their web site is still there but I cannot see my balance details - "Your current balance is £ Error retrieving balance from the server". Lebara don't respond to email and can't get through to customer service. I wouldn't be bothered except I know I'm around £12.00 in credit.
Anyone else had this problem?
