Getir Kept Calling Me With Campaigns but Never Let Me Use the Discounts

I keep getting numerous messages and phone calls from Getir urging me to shop, but every time I attempt to make a purchase, the promotion they promised fails to work. I reached out to their customer service several times to address this issue, hoping for a clear explanation or resolution, but unfortunately, none was given. I recently gave it another shot—went through the entire process, reinstalled the app just to be sure—but still, no changes at all. The discount just didn’t work, and I didn’t receive any follow-up from Getir regarding my concerns. I feel like I'm being deceived by campaigns that never truly deliver. After all the effort and time I've spent, I've decided not to use Getir anymore. I felt utterly overlooked during this experience.
