I have no problem ordering food from Grab until recently I tried to order from Mart. My 2 recent orders have problem, the first one, the promotion was not transparent, saying order a set and get freebies. I ordered a set but they were saying I ordered wrong set. Secondly, i order from Grab supermarket, they just cancelled the last minute and when I wanted to reorder they increased the price. It was ridiculous, if you don't want to give any cheaper price or promotion, might as well don't give at the first place. I have placed order 2 days in advanced to make sure it gets delivered but it was cancelled last minute. Will I place another order and wait to be cancelled again last minute? I won't place new order anymore. And the help center, almost all the time more than 20 queue without any notification that new chat coming. I let it run on background and checked few times and one minute, it missed already. Please fix your help centre!! I think it might be on purpose so people don't get help from here and just let it go. I had to wait 2 hours+ to get answer but it missed.
