A person who davens in a shul in someone’s living room where the rav’s children run around and make noise during davening, which many find disturbing – in the past, the rav has told people to bang their hands on the wall to quiet the children, or to put their fingers in their ears. The rav feels that he is not obligated to address this issue. Perhaps he is embarrassed that his children behave this way. Is it better to someone to discuss with the rav the need to address this issue, or should one simply stop coming there if one feels that the rav is not prepared to address the issue?
In general if you can’t concentrate, so daven elsewhere. Regarding telling the Rov, it depends if you think thre is a chance that he will listen. From what you are describing it looks like you think that he won’t.
