Opting for upgrade when already with idmobile
Email from ID mobile correctly informed me that my 2 year contract is up in a few days. Went to it's site and ordered an upgrade, but this did not include transferring my number. Tried to obtain PAC, but to no avail. 2 years ago I ordered my SIM only from mobiles.co.uk which with ID mobile seem to be part of Carphone Warehouse. Confused that I received notification from ID mobile but won't recognise my existing number, which I must keep. What did I do wrong? Any advice on how I proceed?
