Uber eats - taking off more than what was purcahed for on my card

On Tuesday the 27th August I placed an order for the 50 percent off fruit and veg at the woolies lala ridge in Durban.. R163 was taken off my account. I scheduled the order for a pick up the next day. Upon picking the order up I noticed there was a major price difference and the order was now R343, I asked the lady who packed my order if there will be a difference to pay and she no I have paid via the app. So I assumed once u have purchased on the promo the prices go back to normal. As I was leaving I see the amount of R163 is reversed in my account, I told the manager and said pls check and u have my number buzz me. So after 48 hours uber takes an amount of R343 from my account. When I called the store the manager says that there was an issue with the promo on Tuesday and gave me a number to contact Uber which was for merchants only. I messged via the app for assistance and get told since the issue happened after 48 hours there is nothing that can be done. How pathetic. Shame on u Uber for ****ming people with your promos, if u cannot provide the proper deals then don't bother advertising for it. Pathethic on your side.
