Today I received this email frome shop back. I requested withdrawal on 18 May, rm 20 from lazada app cash back.
Hi xxxxx,

Thank you for supporting ShopBack!

We are really sorry, your cashout request of RM 20 has been delayed! More than 99% of our cashout requests pass automatically, but a small minority gets delayed due to one of the following reasons:

1. Our partner merchants have not paid us and we are in the process of collecting the payment from them in order to pay you.
2. One of your cashback transactiond has been randomly flagged for audit checks

Please rest assured that as soon as the investigation is completed / when we receive our payment, we will process your cashout request in the subsequent batches of payout cycle. This might take 1-2 weeks depending on the merchant.

At your service,
ShopBack Customer Care Team
