All promo code for grab bike/car are broken and unusable. Multiple time i was given a promo code and despite having the condition (location, date, time,) met. it's always gonna give me an error message (error or invalid saying i used up the promo code already, which is false) They'll give you a lot of these promo codes to attract people but it's unusable, just for show. It has been like this since early 2020, haven't used this app since unless for food
