I'm sorry to hear that you're receiving communications about having Smart Meters installed if you've previously said that you don't want them.
Firstly, As Andy65 has mentioned above, the Community is a member to member based forum where you can post and talk to other members, we have a Community team such as myself and you'll see a few others around too, who are here to moderate. As you have seen, I had to remove pictures you uploaded originally as these go against our Community Values. It's not safe to post pictures containing your personal info, so it was in your best interest for me to remove these. Please read over our Community Values here
to understand how to post, and what you should/shouldn't be posting 😊
I have noticed that you've used the word harassed by these communications, please can you let me know how often you're actually receiving these messages? The communications are sent out automatically so it won't be someone sending this out to you manually, however, you really shouldn't be receiving that many, and of course, you're not obliged to have one installed if you're on the variable tariff.
It's likely if your account has moved over to E.ON Next's system recently, you've fallen back into the Smart campaign journey, and that's why you're receiving these messages, you can be opted out completely though.
This is something you will need to get in touch with customer services to have resolved, you can find a number of ways in my signature below of getting in touch, and the fastest ways to do so.
You'll need to request a 'long term opt out' when you speak to customer services. This will stop all Smart installation messages/reminders being sent to you entirely.
Let me know how you get on.
