Manor Ward Labour Councillor Steve McGinnity and Labour Action Team's John Kelly have been contacted by a growing number of bus passengers who say they are being let down time and again by an unreliable 54 bus service.
Residents complained that part of the route was regularly being skipped laving passengers waiting.
Cllr McGinnity and John Kelly both passed the complaints on to Arriva and received assurances that the company would investigate.
However the two Labour Acton Team leaders made a visit to the bus stops which had received the most complaints to discover as many as seven people waiting at each stop along the affected part of the route which included one woman who had been waiting over one hour for a bus.
Cllr McGinnity said: "John and I spoke to the people waiting at the stops and they confirmed that this is a regular occurrence as the bus regularly skips a part of the journey, missing a number of stops.
"The passengers told us that a the bus goes towards Thornton, they are then heading down Liverpool Road and bypassing Chesterfield Road and Brownmoor Lane.
"The passengers waiting at the stops told us it happens regularly. One lady said she leaves the house an hour and half early each time to ensure that she can get a bus to work. When we spoke to her, she had been waiting for more than an hour.
"Another older gentleman had been waiting for the bus to go for to doctor's appointment. He ended up giving up and going home.
"This clearly isn't good enough and we have asked for an urgent meeting with Merseytravel and Arriva to discuss the passengers' concerns."
Labour Action Team's John Kelly said many people relied on the 54 bus to go about their daily lives.
John said: "Most of the people we spoke to really do rely on this bus to get them out and about, to work or for important appointments. But when that service is failing, then it is having a major impact on their lives.
"We want to discuss the concerns with Arriva so they can assure us that the best possible service is being provided for this community.
"In the meantime, if anyone wants to report any problems with the service, please call 0151 531 1193 and we will ensure that Arriva and Merseytravel get the details."
