Uber India — daily fare issues

Every day the amount shown while booking n den actual is coming different. Wid huge value difference. Even after mailing they r nt replying n not returning my money. N it's not matter of error of 2-3 rs, everytime it's 50+ rs types. They r just cheating customers n taking our money. I m daily uber rider. Have been using uber since years but they don't hv any value for customers also
