If I buy stock 269 if I sell it I only get 260 where is the 9 rand going companies ****ing pockets

Look at these **** artists where it's buying at 269 but if you want to sell they only give you way less than what the share is worth only 260 so where is that 9 rand going ill tell you where I to the companies pockets. What **** is this if I sell a share I should be getting the same what someone buys it for this is just a tip of the iceberg I've seen them Evan selling price way less. ****** ******
