The consumer's right to report high service charges

A chiller company (X) in Dubai is charging AED 2/ton while all other chiller companies charge much less (e.g. (Y) charges AED 0.568/ton). So the difference is huge between those 2 companies.

For a 1 bedroom apartment within the same month, X is charging AED 1100 while Y is charging 618 which almost half.

Are there no regulations from the government for cooler charges?

And shouldn't there be some customer rights on how much chiller companies can charge?

Thanks.
