E-on blocks your phone number - you can't call then!!! I want to tell, that I was impressed that if E-on doesn't like you - they block you))) you can't call them any more. We made a contract with them, later should put counter readings in their App, but my mum forget about this. It's our mistake and we agreed, that they canceled our contract (for me even ok, that they sent the letter, dated 08/02 with info, that they canceled from 01/02). And yes, we were as a Client only one month, they spend time for us, preparing contract and consulting. But BLOCK then?)))) firstly my daughter couldn't call, she told, that there is no call. Then me- I could call and communicate, but then call was interrupted and other attempts were unsuccessful- no possibility to call any more. The same has my mum. So they put in system our telephone numbers and made block)))) it's so funny, act like children))) For this company Client is no important!
