BatteriesPlus review: Customer service

Worse customer service I have ever experienced. Rude to me acted like I was stupid. Took bulb I was replacing and tried to tell me I could not use in lamp base the engineer needed it for. I called back to confirm I had the right bulb. It was put on hold for over 2 minutes so I hung up. Called back and did not get the employee that waited on me but he said this bulb would work. Well guess what it did not! The original sales person was also packing. I saw the pistol in his back pants tucked in his waist of his pants. When I saw it he saw me and immediately pulled his shirt down. Is this a safe store to go into... I guess not.
