Nescafe Express Lottery Fairness Concerns After 300 Entries Without A Win

I have been participating in the Nescafe Express lottery campaign regularly and intensively since June until the last day of August. During this period, I bought Nescafe Express cold coffees from different places many times and entered the draw approximately 300 times. Despite this very high number of entries, I did not win any prize even once. This situation has created serious doubts in my mind about the fairness and transparency of the draw system, and I consider it unfair. I kindly request that the full draw system and algorithm used in this campaign be clearly explained and that the fairness of the draw be proven in a way that can be verified by consumers. If there has been any mistake or injustice in the process, I also request that it be identified and that my grievance be addressed accordingly.
