So it's been 3 days since this flash sale and have not yet received the 75 cash back. They had assured me that i'd get it within 3 days when i contacted them on Friday and today i had a chat with their executive and they arranged for a call back. Some lady then called me and it was a 5 min long conversation and it's quite shocking that these executives are not aware of these offers. It took them a while just to figure out what i was talking about and then she apparently escalated this issue to the cash back team who will contact me some time this week. If the cash back isn't credited by Friday then they asked me to call again on Saturday. What a joke
