There is water coming out of a manhole cover & flowing across our driveway

I first reported this problem in July 2024. In September you claimed to have resolved it but you hadn't so I reported it again. You then claimed it was not your responsibility & I should contact Thames Water, which I did. Unlike you they came out the very next day to inspect the issue but they said it wasn't their responsibility either. They said the problem is caused by the blockage of underground drainage channels causing excess water to flow where it can, i.e. into the manhole & out the top. The water then flows across our driveway & this has been going on all winter. It has cut itself a stream bed in the gravel & is causing green slime to grow, Please will you come & look at it for yourself & if you still think it is the responsibility of Thames Water liaise with them yourself to rectify the problem. The exact location is outside Orchard Cottage & The Old School House.
