Family Dollar

I returned 2 shirts for the obvious reason. (They didn't fit correctly.). at the family dollar at ***.on July 20th, 2020. They were valued at 7.00 each. They were new with the tags on bought on July 6th.2020.. The gal handed me back 7.00 plus tax. I said. "Um 2 shirts were returned.& not one.m She said they went on sale. I said the reciept is right in front of you showing a value of 14.60. Dumb store mngr who this gal called said. "We dont jno..how to override it"? I am writing this up & expect another 7.35 to be exact to be refunded to me! This is THEFT !!!!
