UberEats *****ing from people!!!

I ordered a large salad and pizza from Toni's Fully furnished Pizza on Thursday, 29 Nov. We eat at Toni's regularly and know their pricing. I know the prices are inflated on UberEats however i ordered a large pizza and large salad. UberEats then charged me for a regular salad and in addition to the regular salad charged me as an add on, the price for a large salad as well. I ended up paying R 81 for a regular salad AND R 122 for a large salad making the total for a salad R 203 for one salad!!! When i took this up with them, they said that this is correct. It is my understanding that you pay R 81 if you order a regular salad OR R 122 if you order a large salad. When the salad arrived, it was definitely not what you would expect for a salad to the value of R 203. UberEats inist that this is the correct pricing. In my opinion this is theft!!! They have no intention of refunding me and insist that i was charged correctly for 1 salad.
