Can I get a credit balance refund?

Hi, in the process of moving away from Bulb which is a shame as we liked your pricing and app and customer service but the price rises are too high and we could save over £100 by moving.

Would like to request a refund of credit balance please, as much as you normally allow (imagine you keep one months payment in until final readings submitted?). We do regular meter readings so our usage should be fairly well known sonod you can refund as much as possible now and will sort the rest of refund / final payment once we receive the Final bill (which I assume will just come out via DD rather than our fixed amount?)
