Double-Check Quantity in App Order

I keep getting burned trying to get the BOGO Del Tacos.

Finally got the coupon code to not disappear (yesterday's problem), and placed my order on the app. Find just one Del Taco in my bag after driving away. Double-check my receipt and it shows I only ordered 1one

Tested a new order through app for 2 tacos, then customized it, and find out the quantity reverts back to 1 before adding to bag. So, if you want 2, you need to put quantity of 2 AFTER you customize it. Good grief. 🤦‍♂️
