ASUS SA worst service possible

We purchased a new ASUS laptop about 4 months ago for our small online business. Within a week (end of November 2022) of receipt of the laptop it started over heating and shutting down all the time. The company that we purchased the Asus laptop from attempted to contact Asus South Africa or their agents in South Africa. The faulty laptop was eventually sent to an agent mid December 2022 and when this agent was contacted he refused to do anything on the new faulty laptop as he advised that he was too busy and it would have to until January 2023. This agent was extremely rude and abrupt and wasn't prepared to assist in any manner or form whatsoever. Eventually Asus SA or their agent sent someone to repair this new laptop. 2 weeks later, same problem. Fast forward to end February 2023. Still no laptop - no replacement - no credit. ASUS, your company and or agents in South Africa are totally useless, They do not know the meaning of service or politeness. No matter who one speaks to (If they answer the phone) should be fired for one of the worst service experiences I have ever had to endure.
