Gutter specialist rec

I don’t trust gutter that was installed by our contractor. I wish I had knowledge before installation. There is possible leak from the gutter. The hole that water go thr is located on the corner of extended room (roof is slightly slanted)and there is no slanted roof like 30 degree or something. Because I might build deck above the extended room one day. I hope you understand my description,,,I love to know what gutter system is supposed to be as my knowledge before gutter specialist come and check. And what is falling leaves prevention for our gutter? Anyone has same experience? Please rec reasonable specialist who you hired.

Thanks,

Happy New Year to all of you!!!
