Hi. Did you log in to your PayPal account and look to see if there was a credit for that amount, or did you just call? If you requested the PayPal deposit, did you verify the email? The payout request page is a bit awkward in my opinion, and easy to mess up - I did!
Other than that, my experience has been good so far. I have earned just over $122. Twice I have had the money transferred to PayPal no problem once I got the payout thing figured out.
I currently have $14.40 pending. I was concerned because I got nothing after 3 weeks, so I filed a support ticket. I got an email back a couple of days later asking for the order information and any screenshots that were relevant, so I provided those and waited. A few days later I got an email saying they had a ton of support requests and thanked me for my patience. I got another email saying the same thing a couple of weeks later. I never replied or tried to file another ticket during this time. Just a couple of days ago I got one thanking me for my patience and informing me that my cashback would be finalized in July. Yes, that is a long time since I made the purchase in March. However, while Microsoft does give the cashback to you, it is the retailer that gives them the money (from what I understand) since it is their promotion and Microsoft gets a cut for getting people to their website. That said, I am pretty sure many of the delays are due to the return policies of the retailer. Receipt scanning credit happens very quickly, and I have only had to wait if there is a specific item that gets you extra money, like buying a specific brand. It is the online purchases that take time. When they still provided cashback at restaurants it always took a week to clear.
Basically, file one report and be patient. Find out the store's return policy as some places allow up to 90 days for returns. Hopefully this is helpful information.
Good luck!
