2 issues. **Smart meters. Kept being pestered about smart meter installation despite responding to questionnaire saying not interested. Then SP gave my phone details to a 3rd party marketing agency to carry on pestering about smart meters. Then more emails about smart meters followed by email apologies saying some emails had been sent in error. **Changing supplier. As contract coming to an end, this nuisance encouraged me to check alternatives, decided to move. Emails requiring final meter reading, fair enough. But shut out of the facility to submit online readings, "error 403 forbidden". The meter reading had been requested effective Christmas Day, got through to them by phone 27th December. Told I shouldn't have been sent the request for a final meter reading because that comes from the new supplier. What bothers me, the email demanding the final meter readings said if I did not submit them "you could end up paying more". Bottom line, there shouldn't have been a problem, I was perfectly happy until at the wrong end of their shambolic IT/email communications.
