UW have been consistently awkward in my efforts to resolve and overbilling scenario on my elderly and disabled Mother's bill. She's in and out of Hospital and we're having to sell her property to fund onward care. UW have not managed to prove the liability they claim, due to the fact it was already paid to Octopus Energy for that period. She's now being threatened with debt collection activity for money she clearly doesn't owe. This is an utter disgrace. Therefore, I'm afraid, I must report far below acceptable treatment in this matter and thusly, significant dissatisfaction with UW's service, of which she had been a customer for some years. Not to mention a Smart Meter was fitted without her knowledge or consent. Very difficult to get hold of anyone to sort any problems out. Standard automated emails, broken processes, useless chatbot, and don't answer the 'phone. An absolute shower.
