Meter readings passing to previous supplier

I am in credit with British gas who have switched are waiting for bulb to send my final readings before refunding me nearly 900 pound. Please help to tell me if this is being sent

No worries at all @claire446. We can confirm that we have sent your old supplier your first readings with us. Depending on different suppliers, it can take up to 6 weeks for them to send you the final bill. Don’t worry, you should get it soon.
