Extremely poor service at Mont Blanc Sandton City

Good day,

I recently went to the Mont Blanc store in Sandton City on 17 September, and explained a problem I had. The lady who assisted me ensured me the manager will contact me the Monday. No one contacted me or followed-up on my query. We live far and I only come to Sandton once every few months and then we buy enough stock to last him another few months. EVERYTIME my husband needs pen refills he hands me the empty boxes and I go to the store and buy new ones based on the empty boxes handed to the store personnel. I never check if they have sold me the correct items, as I would guess a store such as Mont Blanc should know what they are doing- especially if I give them empty containers. However, when my husband opened his drawer recently to refill his pen, the last two boxes were both different and both incorrect. I went to the store requesting them to please exchange it for the correct ones. Rather than apologising for any inconvenience caused, the lady informed me it is not their problem and they have implemented a new system and they can do absolutely nothing for me. Although the cost might be minimal, out of principal I will take this matter to Mont Blanc Switzerland until resolved. I am extremely disappointed with such terrible service from such an expensive luxury brand!!
