Awful company, I’m changing supplier. Was with SSE for 55 years as before that they were called SEB. They were an excellent company and no complaints in all that time, the system worked like clockwork. Always paid quarterly. After several frustrating calls was told no can’t pay quarterly anymore but could pay every two months. This has carried on for about a year but every time a bill comes (monthly) within days almost the threatening letters start about overdue payments, debt collectors and court orders. I’ve always paid promptly within the time limits. Awful customer service, I don’t think they are properly trained. I can no longer stand their bullying and threats, there are plenty of other suppliers that treat you respectfully as a customer. Reviews say it all about this inept company. They’ve been in the news recently and it is scandalous the overcharging they have been getting away with! Please be warned and steer of OVO Energy!
