Booking doesn’t respect own clients

Booking doesn’t respect own customers, I’ve deleted my account and will never give them my money. I had 7 years old account and in mobile application I was informed that if I will complete 2 trips within 2 weeks I’ll receive genius 3 level. I did mentioned trips and received notification that my genius status is updating and it will take several days. After week of waiting I was received new notification - please complete one more trip to get genius 3 status. After discussion with support what happened they did not provide any explanation and just tried to ignore my requests. After that I decided to delete my account. I spent my money (during push to get genius 3 level) and I didn’t receive anything and my requests to support were ignored. Bye bye booking. Never again.
