Traffic light phasing fault

Good morning. There has been an issue with the set of traffics lights on the M3 J4, A331 roundabout traffic lights for the past 2 week. There appears to be an issue with the phasing which only lets 3 or 4 cars through before going back to red. This is causing queues back onto the motorway which is dangerous.
