Dangerous uneven surface

The tarmac has almost completely worn away on the entry and exit of this roundabout to/from South Lawn Way. I have felt my car losing grip on this surface, and it has become increasingly more dangerous in the last week or so (it is clear to see how rapidly the road surface is disappearing, even over just a few days). There are also many large potholes on the slip road to enter the westbound carriageway of the A63. These road surfaces need looking at urgently, it seems others reported these issues months ago and nothing was done, so they are now very dangerous to drive on.
