The house next door to mine is rented. The tenants have been leaving their rubbish in the back garden, at this stage about ten huge bin bags plus 2 overflowing wheely bins, the rubbish has been building up for more than 3 months. I have called round to the tenants twice and politely explained they can't leave rubbish in garden , health hazard etc. I have also phoned owner of house who said would sort it, didn't answer my last call.
What to do next? Could the council help?
