XPS 13 9370, bad Dell experience all around

So I typically buy Lenovo Ultrabooks (Carbon X1 to be exact) and have been very happy.  But I always research to see if things have changed when I make my new purchases.  This time around everyone seemed to recommend the new Dell XPS 13, so I decided to make the change.  I use have used Dell monitors and always been really happy, right now I have two Dell Ultrasharp 34inch curved monitors.

So I was recommended by Dell to buy the XPS 13 (9370) and bought the 2nd from highest config, I didn't want the 4k touch screen since I was told it drained the battery quicker and also told 8GB of ram was enough.  I have been using this for a month and it is just too slow with the 8GB, lagging on a lot of programs, and definitely when multi-tasking.  Since I was recommended this model by a Dell rep I called up customer service to ask about more ram, they put me on hold and transferred me to sales.  I told sales I wanted more ram and just bought the unit and it was acting really slow and they transferred me to technical support, they told me I needed more ram and transferred me back to sales.

4 hours later, between calling by phone, trying the online chat, and being transferred close to a dozen times I have yet to get an answer.  Part way through I started getting frustrated and looked at what the cost to upgrade the ram was, it was $100 dollars.  All I wanted to do was upgrade my ram on a less than 30-day old laptop.

I asked to talk to a supervisor which no one could seem to do, and at the end, I was extremely frustrated and thought Dell should actually just send me the ram free of charge for really taking a loyal customer and not caring and not having the proper customer service in place to help them and taking up half their day.

In the end, I gave up, I have a brand new Dell XPS 13 (9370) the 1399.99 model and I will probably go buy a Lenovo and use it as a paperweight.  Really disappointed in this who experience.  And if you are going with that model I would error on the side of caution and try to upgrade to even 32GB of ram if possible. 

The machine looks great and really wanted to like it, but I am really disappointed. I have several friends all waiting for my feedback since they were looking at the same machine and now they are unsure too after watching my experience with Dell.
