Bad service at Wimpy Myezo Mthatha

on 19/04/2019 I noticed that I had a free breakfast offer from FNB and was notified that I could go to redeem it at Wimpy at Myezo in Mthatha. I went there with a friend who also banks with FNB and had the same reward. Upon arrival, I asked to redeem it and was told their Y code(if that's what it's called) wasn't working. Disappointed that I now had to pay for our meals, I sat down and asked for the wifi code. Surprise surprise, that isn't working either! The service that followed was slow and to top it off, my meal came with chips that had hair on them(I took a picture as evidence)!!! I'm appalled at the service I got, especially because I could not claim my reward due to technical difficulties that had nothing to do with me. I wasted petrol and went far when I could've just stayed at home or gone to a Wimpy closer to my house and that had working wifi. This is totally unacceptable! You can't advertise one thing then provide another(which is nothing in this case). This ended up being a very time and money consuming exercise that left my very dissatisfied and disgusted with the service.
