I have a question about Irrelevant Searches in Google AdWords.

[Qaideth]

Hello, I have been running Google AdWords ads for a long time, spending around 10,000? - 15,000? on ads. It has both benefits and drawbacks. However, I am feeling overwhelmed recently due to the excessive increase in irrelevant searches. I am only paying for ads that appear in Google search results and maps. My business offers hotel spa services, but I'm starting to get frustrated because of some ridiculous inquiries, such as people asking if we provide electric bill payments or carpet cleaning services. These irrelevant calls are starting to annoy me. Our keywords are strictly related to hotel, massage, and guesthouse, nothing else. How can we solve this issue? If this continues, I will have to stop advertising on Google because almost 70% of the budget is being wasted on these irrelevant queries. Despite using negative keywords, I keep receiving irrelevant calls. Do our experienced experts have any solutions or ideas on this matter? Thank you.
