edgars double charge

went to edgars cbd pmb to buy and as usual i took what i needed and went to the tills and paid.upon me going home i later noticed that i have been charged twice.im not sure if this is how edgars or edcon handles thier business but its ridiculous and such an inconvenience for me as the customer.i had to go back to edgars from home to be reimbursed for the balance overcharged only to be told that they will log a call and i must wait for it to be reversed.this is so disapointing and makes me never wanna come back to this store or any edcon stores for that matter below are the 2 managers i spoke to but never got help kaajal njabulo majola
