Supplier overcharged me and underlivered

I contacted Gordon Spit directly after I saw his advert on Groupon. He advertised the following on Groupo:<br> Choose between these options: <br> R799 for a Spit Braai for 10 (R1 699 value)<br> R1 155 for a Spit Braai for 15 (R2 399 value)<br> R1 439 for a Spit Braai for 20 (R3 099 value)<br> About the Spit Braai<br> Lamb: Spit-roasted, deboned and basted (250g per person)<br> Four baby potatoes per person<br> Fresh garlic bread (one for every five people)<br> <br> I paid and amount of R2800 for 30 people, He initially charged me R3200 for 30 people, but his advert clearly stated R95 for each additional person which mean he should have charged met R2389.<br> For R2800 I received a small square full of off cuts and a quarter square dish with small baby potatoes cut in halve. I was shocked and upset as I have never been done in like this my husband had to go to KFC to buy a bucket of KFC in order to feed all our guest and to prevent embarrassment. This supplier is dishonest and I want to warn customers, I've also asked all my guests to spread the word. I cannot believe this I took a photo of the small shaving dish the food for 30 people were delivered in. Let me know if you want me to post it.<br>
