Terrible company with no robust process in place to ensure their paying customers are cared for. Never contactable, spent all day on hold, both on the phone, on chat and no response to emails. They believe it to be acceptable to dump a last minute hugely incorrect bill on your doorstep of over £430 for one months gas and electric. On top of this the threat to send debt collection agencies to your address if you dont pay. When you, rightfully as a paying customer, want to view your bill to correct their mistake, you cannot view online as the system doesnt work, cannot view via their app as the system doesnt work, or contact anyone on their phone lines (who then play recorded messages, begging you to look online at your Bill's, which of course you cant), so you try and raise a complaint, which goes nowhere. Cannot understand how they operate as a registered business with this blatent disregard for their paying customers, never mind such a large 'supposedly' reputable business. No valid responses or customer care means I happily raise to the financial ombudsman service, which I'm sure are harder to ignore than one of their paying customers.
