Wrong order

Good day

I am very disappointed with the service that I got from you. Today around 2h00 I was passing by from the doctor appointment, I bought Mcfeast regular which is R103.00 how ever when I arrived at work I found that the burger is not what I ordered I was given big Mac. Kindly arrange someone for the right meal and take back the wrong one. I paid more money to get what I didn't order or want. Tried to contact them but number on the website is incorrect, I have contacted customer care still the stor hasn't contact me yet. I didn't have my lunch today. Please fix your numbers, even your customer service gave the same wrong numbers.
