UCOUNT Bad service on checkers voucher

I successfully met a uCount goal, resulting in a Checkers voucher valued at R50, which was set to expire on September 17, 2023. On the specified date, I endeavored to redeem this voucher at the Checkers Woodlands location, only to be informed that it had already been utilized ("burned"). In response to this, I promptly documented the incident by capturing an image of the point of sale receipt and took a screenshot on my mobile device to furnish as evidence to Standard Bank uCount.

It is essential to note that, as per the standard protocol, vouchers are expected to be removed from one's account profile upon redemption. However, I observed that the voucher in question still remained visible in my profile even after my alleged usage.

Subsequently, I initiated contact with uCount's customer service on multiple occasions to voice my concern and request an investigation into the matter. Upon the completion of their inquiry, I was informed that there was a likelihood that I had redeemed the voucher on September 5th, an assertion I vehemently contested. I emphasized that such a usage would contradict the stipulated policy, as the voucher should have been promptly removed from my profile.

My final interaction concerning this issue was with a representative from the complaints department, who regrettably exhibited a condescending tone in response to my concerns. I find it disheartening that, as a loyal and high-spending customer, I have not been afforded the courtesy of an apology, neither for the alleged error on their part nor for the suboptimal treatment I have received. In light of this, I earnestly request a resolution to this matter, specifically the reinstatement of my voucher.
