I would like a corporate email or some other way to contact corporate to make a complaint,

  I would like to start with I have spent an insane amount of time during my vacation to switching to Xfinity.  First, we transport our numbers and don't have service for 2 days because this was supposed to be eSim switch over and it wasn't.  I am getting sims cards in the mail.  We switched on August 31st.  Still don't have the cards in the mail.  We went to the store on Sept 2nd and they did fix them there.  We also attempted to do a trade in with a value of $500 for each I phone.  We were not able to do that and was told that we would have to come back once the third line was activated.  We did this yesterday.  2 hours later we walk out without our updated phones and charged $35 for a restock fee.  Let me tell you why.  The first line went through fine and activated just fine.  Unfortunately, he did not put in for the $500 trade in when he started and could not go back according to him.  So, in order for me to be able to do the trade in I would have to return the phone which cost me a restock fee for his mistake.  Then we got to my husband's line and it came up that the phone would have to be shipped.  Would not allow him to move forward with the phone that was in his hand in stock.  No idea why that was.  So again, two hours later and still no updated phones and it cost us money.  Even before that when we transferred the service I was supposed to get an eSim for the lines and neither one came.  Come to find out the eSims were not done and it was a physical card that was coming.  We still don't have the cards.  We would have went over a week with no service. We went without service for two days until we went to the Xfinity store and they were able to fix it there.   I am currently 3 hours in to trying to pair the watch that my husband added to the account as well.   This whole process has been extremely disappointing, time consuming and stressful.  I would like to know how I can get the phones upgraded without having to have them shipped to our home with the $500 trade in value for each phone that we were promised,  We can not take anymore time off of work to sign for a package and if I order them online it is only showing $70 trade in value.   Extremely frustrated with this whole experience and would like some help with a resolution and maybe a refund for the restock fee or some kind of compensation for all of our hassles.  Two trips to the Xfinity store and multiple hours of time without what we went for is just not appropriate I would say.  I also want to ad that I asked for a corporate email and was given a bogus email that bounced back as undeliverable.
