How to contact corporate customer support to get resolution for a Xfinity error

On June 16 I signed up for Xfinity 1 Gig service...the one listed as recommended in the attachment. There was a deal on last month where the monthly cost was $55 for the first 12 months then $65 for the next 12 months. I have email confirmation to prove it.

On July 2 my service was turned off. My bill says I requested cancellation ("We're sorry to see you go..."). I did not and the cancellation was a severe inconvenience to my family at time where I was out of the country and unable to fix it.

I'm still out of town but today I called to get it fixed. The person I talked to could access almost none of my information. It wasn't her fault and she was nice about it, but it was an unbelievable waste of my time and frustrating because the only way to restore my service was to sign up for a far inferior deal because the agent was unable to reactivate the original plan. I just want the service I subscribed to restored for the same cost. I need you to either fix this or give me a direct way to escalate this to the highest level via email where I can simply send the two Xfinity confirmations (the original at $55/month for 12 months then $65/month for the next 12, and the new one at $70/month for 12 months and then $109/month) as attachments to somebody with the authority to fix the issue. I'd also like Xfinity to provide a billing credit for at least month to compensate me for the inconvenience and my wasted time.

Xfinity's software systems and processes are in absolute disarray. Web pages don't work, login's get stuck in a loop etc etc. Billing information does come up. You don't know what packages your customers have had, and often have no idea what equipment has and has not been returned. This has been the case for years, and friends and family have had the same experience. You must know this, but obviously it is not worth caring since most of the time the customer takes it in the shorts (as my partner did when you lost her Apple Watch and charged her for not returning it; she wasted hours trying to get a refund; it showed up in your store 18 months later). I moved to Century Link for a couple of years because of this, but they are equally incompetent and broke my service and responded to my outage notification by saying, "Yeah we know about the issue, you need to upgrade and give us more money to fix it" I'm guessing this is why the two companies feel they can get away with the shockingly awful state of affairs. Honestly, neither company should be in business, and if another entity existed to challenge you both, you wouldn't be.

Way beyond disappointed. Please give me contact info for someone as high up as possible.
