Monster Notebook Huma H4 Laptop Wi-Fi Issues

I recently purchased a Huma H4 V5.1.10 laptop from Monster. Despite being brand new, I encountered a Wi-Fi connectivity problem that went unnoticed during the alleged pre-check. While the Monster Tulpar T6 connected flawlessly in the same location, my Huma device struggled to connect at a significantly lower speed. To address this issue, I made time amidst my busy schedule and dropped off the product at the Kartal service center this morning, demanding an urgent inspection due to a service-related problem on a brand-new product. However, during my noon conversation, customer representative Mr. M**** informed me that the process had been queued, with a standard service time of 20 days. I was met with indifference. I find it unacceptable that a product I purchased new was delivered without adequate inspection by your company, and now I'm left to suffer the consequences. Now, I want to return the product because I'm not getting any information. I want to speak to an authorized person and request direct contact from a representative to explain the situation over the phone, instead of receiving standard responses.
