I lost my sim and cancelled the package as per the call centre agent. I have paid for that package and it still has my full monthly allocation. <br> The agent told me I will have to sign up for a new one and they will transfer all my data. No problem.<br> <br> When I finish selecting my package, it states that I will be billed. Why? I was billed on 2 Jan and all I want is a simple sim swop. <br> <br> My bank account must not be touched, but i want a replacement. Alternatively, transfer my data to my other contract I have with you. Why do you make sim swops sound like rocket science?
