I had not topped up for months as I experienced a bit of poverty. Now I'm back on my feet, I went to try top up and my PAC code expired. They refuse to re-issue another PAC code and tell me I need a new number. I'm so angry, I've had that number for my whole life. Any other provider keeps your account and ensures a new PAC code even after expiration. Absolute disgusting. Spoke to 2 representatives, neither would help me. Worst provider I ever experienced.
