I was informed today by AGL that they do not refund solar credits at all. When I said I had enquired last year and had received a credit, the lady said I hadn't. I have been receiving refunds each year since 2014 and still have some of their notifications that arrived with a cheque. She said that it had to stay in my account to pay for future bills, but I have'nt had to pay anything for years and would really appreciate a refund after this bad year. Hope someone can help.
