Money wasted

Super upset... Ordered Mr delivery Roccomamas however it gave an error msg saying my order could not be accepted at this time so I ordered wimpy instead... When my order got delivered I thought it was wimpy because that order went through....turns out it was Roccomamas and I tipped the guy 100..mind you my order was 200 there initially...my order at wimpy was 270...and that's what I thought I was paying for... so I only realised this when I started unpacking the food and then the wimpy delivery came...both orders actually went through costing me 600 total for myself and 2small kids...I'm not one to complain but **** man...
