My account was in credit by over £560 when I decided to leave Bulb in August. They said I would have to wait 2 months to have my overpayment refunded and said it would be paid back to me by 10.10.21. I contacted them 11.10.21 to ask why I hadn't been refunded. On 12.10.21 they said I had caused the delay as I had cancelled my DD. No one told me this would interfere with my refund. It would seem they wanted me to continue to pay £150 per month into a closed account which already had a credit of £560, this would have taken my credit amount to over £800. My final bill was £55. It is now 13.10 - 3 days after I was due my refund and I am still waiting to get my money back.
