Poor customer service

I am the owner of a Galaxy Note N8000. This cost a huge amount of money new. What separates this from other tablets is its ability to use a pen stylus. However the pen stylus does wear out at the nib end. I went to multiple cell phone shops (e.g. vodacom etc...). None of these stores had the nibs or stylus. I was then referred to the Samsung store in Pavillion Durban. They too did not have these. I was told by the salesperson that he will contact me when they get stock. I have been waiting for over a month and no response. This is poor customer after sales service. Now I cant use my Samsung product as it was intended to be used with a stylus. This is Samsung's donwfall - not supporting their devices during its life cycle after sales. They took my money when I bought it, but will not support me to continue using it. This is just wrong. I will switch to another brand.
