Bad service

Stupid system, I went to Tops today 27/03/18 , the is special on Savannah R62.99 but on their system is R79.99. manager by the name of Thokhozani said she can't do anything but I asked why did you put those catalogue out if is not loaded on system. She was very rude and moody. I asked why can't she do it manually. Weak service.
