Absa Rewards Advantage Challenge not offering selection options

After completing the Absa Rewards advantage challenge, I got a message that I can choose my meal voucher from one of the listed food outlets. When I clicked the selection option, there was ONLY ONE option already ticked for me which forced me to donate my R50 voucher to Gift of the Givers. What is the point of giving me a challenge and denying me the opportunity to exercise my options as the only option was an Absa disaster relief partner? I have been sponsoring several csi projects over the years and I find it ********* to be forced into donating to your preferred csi through false pretence.
