Mrs Jim and I live in a converted victorian house, which is now turned into two flats. Both flats share the same address and there is no distinction between them (e.g. top/bottom flat or flat A/B No XXX Road) and we share a front door We also own a TV licence and pay by direct debit. Today a random letter appeared out the blue from TV licencing threatening a visit as there was no TV licence present. The thing is though that it was adressed to 'Flat B XXX Road', which is not an address either of our flats has. We assume downstairs has a licence given no 'angry letters to say you've not got a licence' have ever turned up at the address before, which they are usually good at. From a serious perspective, given they've sent it to an address which doesnt technically exist, how can they conduct a visit, or issue proceedings against an address? Also if they do start to be difficult, can potential action have any impact on my own flats credit or other ratings? If they do turn up, is there anything I can say or do to really wind the little ******* up, as I utterly despise them (something to do with them harrassing my grandfather for not paying his TV licence due to his having the audacity to die several months previously and their ignoring plenty of reminders to that effect) and want to annoy them as much as possible. Any ideas on what I can do, both seriously and also to have some fun with the scum?
