Recently I signed up to Ovo energy and input the address incorrectly and forgot to include that the property was a flat. This flat has a different NMI than the original property. I need to change my am supply address on OVO but currently the phones at Ovo are not receiving any calls and I have not had an email reply.
Would it be best to cancel my account with Ovo, which would be within the 10 business days of signing up), try using the switching properties, or another idea.
Any help would be much appreciated.
