Really Now. Bad Attitude

Went to the Ackermans at Boulders Shopping Centre in Midrand to buy snug boots that’s on special for R149.90 for two pairs. When I went to pay for the boots the cashier Frank said that the special is no longer available. I asked why are they still advertising the special he told me I can try Ackermans at Greenstone maybe they still have boots available. When I spoke to the manager by the name of Lufuno, said that the system only gives the discount on purple snug boots and not all snug boots. I told Lufuno that the flyer displayed on the window says any snug boots. I asked Lufuno to call the head office and inquire, he told me to call the head office myself. I had to call him back several times to finish our conversation but he kept walking away. Lufuno is rude and not able to handle customers.
