Metropolitan is a disappointment

My mom lost his husband in 2019,he was no longer working because he took an early pension because of health reasons and we sent all documents needed including his papers from labour department which they wanted 2 weeks back no one is getting back to her about the claim.we constantly have to visit their offices for answers but no one's knows they only tells us these things takes time and it's been 2 years already . I'm very disappointed really.
