Dis-Chem, Great Store Lacking Professionalism

I went to the store in Centurion mall and I ask them to check a price for me to make sure it's as written on the shelf. The handwriting on the price was so bad they made R119 look like R49 but the shelf also said 20% off so I just wanted to check. This was not the problem, the real problem is that instead of fixing the handwriting on this proce tag, 4 staff members proceed to mock me and laugh at me from across the store for misreading the ********** handwriting effort. Completely unprofessional.
