Not Motorhome info, but hope it my help sometime.
- My old Smart Meter does not work , Phoned E-on on normal Customer services 4 or 5 times over a year , all sorts of excuses why it has not been replaced ,
- Phoned Customer Services today and mentioned I might put Solar Panels on Roof ,the guy immediately gave me their "Feed in Tariff Phone number " I phoned them ,and she said they will come between 12 noon and 5pm Tomorrow to change meter(S) !! connecting to right Guy was a joy after telling him I had emailed Ripoff Britain which I had!!
