Family Dollar complaint: Unprofessional and no countability

I looked at a sign inside the location that Pepsi products were on sale for buy two get one free. I go to the register and they tell me that Dole lemonade is not a Pepsi product so I have to hold up the line to prove it was indeed a Pepsi product. The manager looks at the sign and tells me that I had to look on the app and clip the coupon. I stel out the line to find the coupon without any assistance from the employees. Finally one of the ladies stocking comes over and noticed that the sale was for last week and no one bothered to update the sales by replacing the ads. The manager said nothing after seeing the mistake. She never said I apologize or anything. I spent 30
Minutes searching for a coupon that didn’t exist. I posted a review about the incident but i have to assume that the management team never replied to my complaint. The lack of a response is a reflection of how serious serious they take up the issues. Since Family dollar don’t respond to complaints, I will not continue spending money at a place that cares nothing about customer service.
