Frustrated with Plumber

[L. Brown]

Hello BP,

I need some advice. I recently bought my first home, which is a house hack. There have been some fairly major plumbing issues. I didn't have a plumber that I knew of, so I went on to Task Rabbit. He came and did some work but continued to experience plumbing problems. My realtor (who is also an investor) recommended a plumber to me. He does very good work but he shows up at least 3 hours late to the jobs which I hate. My realtor said this is how contractors/specialists are. Is this true? Are they that unprofessional? Do I keep looking for a plumber? I'm extremely frustrated.
