Gas meter from joining


I joined bulb from British gas and Edf for gas and electric. When I signed on at bulb I entered both my meter readings to get final bills from old suppliers. Just had my first statement of usage from a week ago and whilst my electric reading was from when I started at bulb the reading i entered at the beginning, 0203 for gas, was changed to estimated at 1111. I have no idea how this has happened as I clearly entered the two readings when asked to by bulb when joining. I still haven’t received my final bill from British gas either which perhaps is due to this 1111 estimate from my first bulb reading (which I entered as 0203) any help would be greatly appreciated. Thanks.
