Montblanc Sandton disgrace to the brand

I am extremely disappointed and dissatisfied with customer service at Montblanc Sandton store. My son took my pen (augmented paper pen) to the store (2 or 3rd April) as I had dropped it and it’s not connecting. The store said they would revert regarding repair or replacement options. Still no response. I subsequently sent an email and still no response. This is totally unacceptable for a premium brand!
