i wanted to do a pre order but somehow the merchant that i choose has grey out this function, so i asked for help through chat, 1st call, forgot the agent name, send me a link and asked me to follow the step which i did but didn't work.. and somehow the line was disconnected. 2nd time the specialist was Maria, she asked me to uninstall my apps, which i also did but it did not work....during our chat, i was slow in response for 5 mins, they disconnect the chat... then i have to call the 3rd time the specialist was Juls, repeat the same steps was given by Maria.. i mentioned that i have already did and again when i am slow in response, they close the chat. i tried to connect again but this time no matter how many times i tried, could not be connected, i suspect they blocked me. One simple questions could not be answered in 3 calls, i felt like i am talking to a robot who keep repeating the steps and not listening to me who have tried what they have suggested and analyse my issue and i felt they are eager to close my case. Ended up i order with another platform - hassle free. i will nvr use GRAB for pre order anymore.
