Customer Care issue

I placed an order on 03/29/18 on Dell Outlet for an Inspiron 7577. I received the laptop quickly and without issue. I was not able to test the laptop until the following evening. Upon doing so, I realized that the GTX 1060 in the laptop had failed. I reached out to tech support who agreed that there was a problem present. I was then transferred to paid support and pitched a different warranty to cover software issues, which i declined. The following day I spoke with Customer Care and was assured that I would receive a replacement laptop within 3-5 days. I received an email stating this, along with a prepaid shipping label. I sent off the original laptop the next day. I soon realized that I would not be receiving my replacement since I received no tracking updates or information from Dell. Calling Customer Care always resulted in being told they are waiting on a replacement to come in, or awaiting confirmation from the "back end". I was told that a case manager would call me. The case manager never did call. Instead sending me a couple emails over the course of 3 days with the same information every time. I stated that I would also accept a different model if the specs where comparable. No response. Today I called in and received the same story. I decided that I would like my money back. Not because I was unhappy with the hardware, but that I was tired of the run around from Customer Care. Now I am being told it will take 2 weeks to get my money back. I would have been perfectly happy if I could have just received a replacement laptop in a timely manner. Especially since I have seen equivalent machines come and go from the Outlet while I wait. I purchased this laptop based on my previous good experiences with Dell hardware. I needed something reliable for school. Now I am stuck waiting for resolution. As I stated before, I would be perfectly happy with a replacement laptop like I originally ordered, or a refund. I can not afford to wait over a month like I have read from other users. If there are any customer care agents in these forms that can help, I would love to hear from you.
