Terrible company . . . avoid at all costs! They keep your account hundreds of pounds in credit and refuse to refund it claiming that they need to keep it for winter. When you try to leave they hold on to your credit for months despite this being against Ofgem rules. It is impossible to speak to anyone about it but their phone lines are constantly blocked and the chat system doesn't work. They are blaming the pandemic for not being able to answer the phone but this has been going on for over a year now and other companies are managing to speak to their customers but Avro are just trying to save money by reducing staff levels and offering a terrible level of service. We tried to make a formal complaint but they ignored the emails. When we left a review they contacted us asking us to remove but I refused. They then said the would not consider our complaint and considered the matter closed. I have have asked for a deadlock letter several times so we can take the complaint to the Ombudsman but they just ignore the requests. The truth is they want to use their customer's money to improve their balance sheet and as an interest free loan!
