Despite their insistence that loyalty matters and having spoken to them several times. The proof speaks for itself. Loyalty means nothing and when they use that word, that's all it is, words.
Your lack of loyalty has just lost you a so-called(by yourselves)loyalty customer

Hi Desmond,
Thank you for your feedback. We’re sorry to hear that you feel disappointed by your experience.
If your comments are in relation to the welcome bonus, we’d like to clarify that this offer is currently available only to customers who are switching to firmus energy from another supplier. This is a standard introductory incentive designed to support new customers during the switching process, rather than a loyalty reward.
We understand that this may be frustrating, particularly for long‑standing customers, and we appreciate you sharing how this has made you feel. While promotional offers do vary, we value all of our customers and your feedback will be shared internally so it can be taken into consideration going forward.
Thank you for taking the time to raise your concerns.
