My Kuveyt Türk Refer and Earn Code Is Useless

I want to send an invitation link for the Kuveyt Türk "Refer and Earn" campaign, but it says that my customer role is not eligible. I would like to know what type of customer I need to be to participate. I haven’t been able to get any information from anywhere. My invitation code is going to waste, and I can’t benefit from the campaign. I would appreciate it if I could get a response as soon as possible.
