Hi ive now had the same letter they saying they have evidence that another adult live in this house. I have a partner but he only stay weekends nothing of his letter/clothes are here. I still get bills/solicitors letters come here for the other tentent. Ive not called them up yet its so upsetting as I called tax credit up to say my partner had moved in full time from 19th jan but they said I had to wait for this letter to come and phone them up. They want all my bank/bills stuff right from april last year. Im hoping its just to do with the other tenrent that used to live here.
