What a dumb app. So because I changed my phone number I can't receive OTP to access my club vistara account?? Your IT director must have worked for some bank in past and just went with a flow. Why so much security? To protect my credit card details? Those details are known to every app on my phone from YouTube to Zomato. What an inconvenience. Also asking for a CLUB ID. Do I just have a tattoo of that number on my forehead? Your app should be customer centric and not Vistara centric.
