Complaint regarding dirty defective equipment

I ordered an "upgrade" replacement box from my television. It was sent via UPS. I wasted a day yesterday waiting for the delivery, it finally arrived after 6 pm. When I unpacked the "NEW" equipment I could readily see it was not NEW. It was also dirty. I followed the 4 simple directions to hook up the new equipment. It did not work. I spent the next almost 3 hours with three different Xfinity assist people trying to "resolve the issue" I kept insisting that the equipment was defective while they insisted, they could "fix it". They finally agreed that I needed a replacement to the "NEW" equipment. 

Today I had to drive to the local office and exchange the equipment. Upon arriving home and unpacking the "NEW" equipment I found it so dirty I had to use a cleaning product to be able to handle it. It did however install quickly and easily. So far it is still working.

I have been a long-time customer for both internet and telephone service. I was so disgusted and disappointed with this latest extremely time-consuming fiasco that I am seriously considering changing all of my service. The waste of over 8 hours of my time, the disgusting quality of the "new" equipment and having to drive across town to get what I should have received is simply not acceptable service. 

I would like to know what Xfinity intends to do regarding my complete dissatisfaction with this interaction. I will wait to hear your response before making any decisions regarding my continued [patronage.
