Be very careful with Uber.They will sms you promotional codes but when you apply them they never work.Uber also does not have a call center so your queries are never heard.Even if you complain on the app they have this automated flag messages which are totally irrelevant and does not serve the purpose.Ola cab service they have a call center which addresses the customers grievances.We need to complain regarding Uber to the competent authority regarding cheating, manipulating and misguided commuters
