6/3/22 I placed an dinner order supposed to deliver at 8:30pm but app notified me 2 time of delivery postpone which is 1.5 hrs lateness so I tried to cancel but the cancel button not function and called customer service 9 time but no answer.Despite I had also chatted with driver to cancel the order but she still delivered to my door late at 10:00pm after we bought & ate other food. The next day I contact grab again for refund but they only give voucher RM 15 but dinner order is RM 100+ so 😠
