Does not delete from my phone. Review on Google Maps

In Google maps. They now invite people to write reviews and give ratings but in reality hide them. Reviews are hidden and ratings are uneffective to effect the overall rating of say a store. I visited a departmental store one time and I bought a chocolate. It was little unshaped. I told them regarding this next time and they did not wanted to agree to their fault. Instead blamed me because of outside heat. Now How could be a chocolate melt and freeze again without freezer during summers. I did not kept it in freezer. Now I started to write a review and when I checked it. I did not found my review and rating. When I noticed overall ratings. I came to know that my rating did not had any effect on the overall rating even. This is the huge amount of hate by Google. Just ruining customers. Application of Google maps has always been pre-installed in android phones and undeletable. When I do not agree to Google maps then why would they force me to use it? I do not know about such a good rating of this service on this review website. Maybe people get something from Google. I do not get anything. I did not found the concept of this service correct as it comes pre-installed and encourages people to become local guides for some points like in a video game. Features and functionality are ok. It is easy to use. Help and support is not good as I did not received any response from them except ingenuine response of their search engine when I wrote a review on their play store. Look and feel is ok. It is not value for money because it only uses people to write reviews and give ratings.
