need immediate assistance from the executive customer service team

We have been Comcast/Xfinity customers for over 30 years and every year, without fail when we return to our seasonal home and remove the seasonal service hold, we are without internet and TV service. EVERY year. However, this year was the worst of any of the years. We spent over 28 hours troubleshooting, on our own, with technical support on the phone, finally a technician came to the house (with an almost one week delay between the call and scheduling the visit). The technician spent an hour in the house - got the service running right before he left and within minutes the service was unusable again. We then spent another 6 hours trying to get it to work on our own and working with a technician on the phone, but to no avail. A second technician appointment was scheduled but we had to wait almost another week for that to happen. At this point we were without service for 28 days which is outrageous for a service we are paying over $200/month for and was obviously a huge inconvenience and source of frustration. Ultimately, my husband was able to figure out a fix and restored the service on his own just before the scheduled technician appointment. 

At that point, I got on the phone to xfinity customer service/billing again to request a credit for the almost one month that we paid for but did not receive internet or TV service. After spending almost an hour on hold and with the CS rep, I was told that I would need to wait until the bill generated before they could put in a request for the credit. So, I waited... I then called back again, spent almost an hour on the phone with a CS rep who could not provide any assistance and when I asked to speak to a supervisor, she hung up the call. So, another call to customer service finally resulted in a representative ("Sree") who committed to put in the request for a full credit for the days we were without service. She provided us with a case number ([Edited: "Personal Information"]) and assured us that she had "raised the credit request" and our account would receive the $228 adjustment for our 28 days without service within one week. We even received a credit confirmation #[Edited: "Personal Information"]. So we waited... When we received our next bill, it is for the full amount and there is no indication that any credit request was ever raised. 

It is truly outrageous that xfinity would treat their customers this way. With over 30 hours spent by a long time customer, countless calls and inquiries into your technical support and customer service, having calls "dropped" and not receiving promised call backs from supervisors and still we have not received a fair resolution to being without service for 28 days. It is such an insult as a customer to be disregarded and treated so disrespectfully.

We need to hear from someone in the executive/office of the president customer service team today so that we can resolve this error before our bill automatically processes for payment in 3 days.

Thank you in advance for your assistance.
