DELL REFUSES REFUND

My case is not resolved. I ordered a Dell Precision 7710 XCTO BASE on 1-26-17. It arrived mid February 2017. Service Tag was xxxxVF2. The machine worked fine for about 10 days, then stopped communicating with any network (WiFi, Ethernet, Bluetooth, etc). I spent several hours on chat sessions and phone calls with Dell Tech Support and after several days of diagnostics and frustration, Dell finally decided the machine was defective and shipped me a replacement machine. The replacement machine arrived March 15, 2017. Service Tag was xxxxYF2. The 1st  machine was returned and received in Lebanon Texas on 3-24-17. The replacement machine worked perfectly for about 10 days also, then displayed the same bad behavior as the 1st machine (network communication simply stopped, out of the blue). Again, I spent several hours on the phone with many different Dell Tech Support personnel who attempted to ascertain what was wrong. As their attempts at correcting the issue did not work (over several more days), I called the Dell Returns Department on 3-30-17 and arranged for a return of the 2nd machine and requested a refund. Jose Iraheta filled out all the paperwork and this took another hour of my time. The reference number for the return is 94xxxx170. On 1-31-17 I received a phone call from Jose Iraheta (Dell Returns Dept.) indicating that my return was not approved as it had been more than 30 days from my receipt of the original machine. How does that make any sense as I waited 20 days for a replacement machine to be built and shipped? I have spent the past 6 days receiving emails from Dell Tech support telling me my issue has been escalated, but that a return and refund is not an option. Obviously there is something wrong with these machines which Dell was not able to determine and cure. I gave over 40 hours of my professional time towards the effort in helping Dell Tech Support try to resolve the issue. I simply cannot afford to waste any more time and simply request a refund. Right now I am out $3500 and have a useless unreliable machine I wish to return for a refund.

My Over-all Dell Experience is currently very bad. I have been the proud owner of many Dell computers over many, many years, but this entire experience has been just awful. I hope whoever is responsible for reading these posts can offer some good news.. Thank you.
