Customer service representative hung up the phone on me because I refused to repeat myself a third time. When I called back to explain to another representative that the 20% coupon off entire order was visible prior to paying but was removed prior to charging my card, the representatives lied and stated sale items can't get a coupon sale also. I told them I duplicated my efforts and can screenshot it taking off both discounts and the rep ignored me and kept lying. I asked for a supervisor and she came back and said a supervisor won't speak to me because prices change at random and they can't control that. The prices never changed in an hour. The 20% coupon simply wasn't applied. The resolution was for me to charge the entire order again & hope the 1st order from an hour ago doesn't ship from the warehouse & gets canceled. All I wanted was a credit for the difference of est. $59. I definitely wasn't charging over $1000 twice without a guarantee of a cancelation.
