Snickers Promotion Rejects My Valid Receipt

I purchased Snickers products from a store participating in a Migros promotion. For this purchase, which I made on November 30, I uploaded the official receipt to the campaign system through the app as required. However, even though I entered the receipt into the system, I receive an “Invalid” error every time I try, and the system does not allow me to try again.

Even though the document I have is a completely valid official receipt, it is not being accepted for the promotion and my submission is not being processed. Receiving the same error message every time gives the impression that the promotion is not functioning properly or may be unreliable from a consumer's perspective. I am left at a disadvantage because Snickers has failed to manage this promotion properly and there is no accessible customer service channel to address the issue.

I request that my right to participate in the promotion with my valid official receipt be recognized and that, as compensation for the inconvenience I have experienced, Snickers send me a complimentary apology package.
