Hi. I have had a call open with you for weeks requesting a switch from pay as you go to pay monthly which has been blocked for some as yet unexplained technical reason. It was escalated to a back office IT team and has gone nowhere - I doubt anyone has looked at it. I have chased it via your contact centre multiple times. The last time I was told it would be fixed by 5th January. It is now the 6th. Pay as you go is due to stop working for me on the 11th. Please can someone fix it for me?
