Highly disgusted with KFC and their customer service

Hi there. I bought the Family treat 10 piece for R199.90 As well as the streetwise 5 for R79.90 at KFC on Saturday. I didn’t receive my whole order. I only realised when I got home that there were no French fries . I complained on KFC Facebook page about it. They message me back and said they will send me a R50.00 voucher. After I spent R279.80 at KFC. Monday I messaged KFC on Facebook to ask when will i receive the voucher code. They respond and said that they already SMS the R50.00 voucher to me. I’ve let them know that I haven’t received any SMS yet. So I asked them if they could resend the voucher code to me, or they can also email it to me. They said to me that the SMS was already been sent and will not send it again. I still wanted to respond back on the Facebook message then I realise I was blocked on Facebook and Facebook Messenger. I’m highly disgusted!! Is this the way you guys are treating your supporting customers?? I will never support KFC in my life again, even my family. And I will make sure everyone will know about it on every social media platform..

I never got my R50 voucher which I believe it’s a disgrace after I spent so much more.

Would like to know what are you guys going to do about it! as a regular KFC customer this is the way we get treated.

I would like some feedback asap..
