Dollar General complaint: mistreated by managment

on the last 3 times i have visited the store, the items I have taken to the check out ring up a higher price then the shelf advertised. When I brought it to the cashiers attention, all 3 occasions I have been yelled at, cursed at, refused service, thrown out of store, and threatened to have the police called on me. I have done nothing but expect to pay what is advertised. They have made it seem like I come in and change the items around and when I tell them to go look at the video they threaten to call the police if I do not leave. All of this being done in front of a store full of other customers. It has involved the manager (peggy), and the assistant manager as well. Is this how you customers deserve to be treated? I have been in customer service for 32 years and I wold have been terminated on the spot for treating customers this way. I am not the one who is mispriceing items on the shelf but I do expect to be treated with respect and receive the item at the price advertised on the shelf. I would understand if it was a mistake and someone set the item down in the wrong place, but in all 3 of my cases, there were several rows and multiple items in the mispriced spot. this was clearly a problem done with stocking. I would like a follow up on how these 2 employees are being dealt with. Until then I am telling everyone I know to not shop there.
Thank you for your time,
