Terrible Service from Vodacom Shop Nelson Mandela Square

I received terrible service from the Vodacom manager, Ally at the Vodacom Shop at Nelson Mandela Square. After numerous calls and messages he has stopped responding to messages and calls regarding a defective product and is not even trying to help or advise on the way forward. Very unprofessional service. The previous manager was much more helpful. After paying premium prices for apparently premium products, we as customers deserve premium products and services. Im extremely disappointed with the level of professionalism and lack of respect from store manager, Ally and will be taking the matter further with Vodacom and Samsung to assist in finding a solution regarding the defective product sold to me by this store.
