Stop Uber company in Cape Town

Uber Cape Town South-Africa is worse than bad. Please look into their twitter account and see how much bad vibes they created in customers. Is it possible to stop them from running a business in Cape Town please. They cause me to walk home because they can keep no part of their side of the deal as company to drive customers. Even when i booked a ride no one came to collect me on the set time. Its very bad. Review them please and take legal steps against them
