Wimpy Stilbaai staff are not trained properly.

I was sent a birthday voucher by this company for a free desert on my birthday. Unfortunately their staff is clueless about how it works. I tried to explain to four people that I redeemed my voucher via their app, but this was not accepted and I was made to pay for it. I eventually gave up and walked out. I told them that it is my 60th birthday and that this treatment has spoilt my entire day. Bad, embarrassing and absolutely unacceptable behaviour by four staff members trying to prove me wrong. Never again will I be made a fool of in public by Wimpy who sends me an invite for a free desert and then made to pay for it.
