Booked a ride to  Central Festival mall last week and the fare was quoted as 103 Baht.  After I completed the ride my card was charged the 103 baht and then a second charge of 62 Baht was made and this was classified as "Other".  I messaged the driver and he said it was a system error and I would be refunded.  I emailed Grab's alleged customer service and I got an automated reply that the isssue is being reviewed.  So far "radio silence" from Grab.

 

Anyone get the additional "other charge" after completing a Grab ride? 

I've had it happen 3 times both in CNX and Vietnam, in each case they added a small amount in "other", hoping it would stay below the radar, as I have payment linked to a debit card but by doing that, "other" is shown as a separate charge. In all 3 cases I reported as a problem via the app and all 3 amounts were credited.

The reply itself took around 10 days, but you can check on the app it will show as in progress or completed.

I must point out, these charges were very isolated, only 3 in 100s of rides and driver initiated, not Grab policy....
