Terrible customer service

Terrible customer service , in store at the Umhlanga Crescent branch . i had purchased an item which when i arrived at the till point the price scanner more than twice what was advertised on the shelf . the supervisor escorted me to the isle to check why this happend and found the item was in 2 or more locations with different pricing . when the isle person was called the supervisor walked away and was not seen again , the isle person "hector" said i cannot help you because the correct price in there at a different location. it is not a matter of just the price being different but they way i was treated and i felt embarrassed in front of other customers because i have also held up the line for some time.
