Third class Inspiron 16 5620, third class experience with customer support

I purchased two dell Inspiron 16 5602 Core i7 16 gb ram Laptops. I purchased them for business purpose. When I attended a virtual meeting, my voice was getting so much fluctuations. I thought it can be the issue of network. Then I tried to attend the same meeting with my personal acer laptop (7 years old), my voice had no fluctuations with that. I tried to attend the meeting next day and I got the same issue in every meeting. I purchased the second laptop for my colleague and that one was having the same issue. 

Now the worse thing started. I checked for dell online technical support. There is a Service "Find My Laptop", I clicked on that and it find my laptop's Service Tag but that service Tag is not recognized for the support. I tried to connect customer care through call. I tried to connect at least 10 times with customer care executives but every time they take my service tag info and express code info and then they put my call on hold and then after sometime call get disconnected. I got no response back from them.

Then I tried to reach support on WhatsApp dell channel. I described my issue and service tag issue to them. They told me they will register the service tags. Even after two working days, they didn't register my laptops. I am facing a lot of difficulty but the only thing I can say to them. Please do it as quickly as possible. I am feeling helpless at dell.

I tried to put request to replace this laptop so I raised a case to the responsible team by going to order details. I got the below mentioned response for the same.

This is just an auto generated response they are sending in every email. At last I thought to put that on social media and have put this on dell official channel. Hope they will recognize it.
