I had 2 declined transactions (merchant declined it).
Money deducted from GrabPay Wallet and NOT refunded. Been 2 weeks now.
Anyone faced the same issue?
As mentioned in this group repeatedly.
Don't use Grab Wallet / GrabPay MasterCard with per-charge pre-authorization transactions (eg in ComfortDelgro app for every booking) or transactions that may be refunded.
GrabPay MC doesn't auto refund the deducted amt, even after Merchant did not post the transactions (eg. did not claim the pre-authorization charge), refunded, etc.
Grab Support will make u wait for 7 days (the default merchant post period), aft that u need to provide PROOF from the merchant that they will not claim the pre-authorization or they've refunded the amt. Else Grab will not auto refund back the unclaimed charge amount.
Unlike banks' credit cards: Banks will auto refunded the charge amt, once the merchant didn't claim the pre-authorization amt aft 7 days or when the merchant refunded the amt. For GrabPay MC: Whenever there's a refund or unclaimed pre-authorization charge, it's the users' responsibility to report and proof to Grab, else you won't get back the money.
