Welcome to the community and thanks for posting. Sorry to hear of your experience with us thus far. But you are in the right place. What we can do here is escalate your case directly to our engineers. Before we go there, we will need more recent speed tests. It's just apart of the process. Based off of your case notes, the previous tests were done around the same time of the month in September. We would like to see a well rounded batch of tests throughout the day, for a few days before escalating. Head over to www.testmy.net
. I recommend creating an account there before running more tests. That way all you'll have to do is post your unique link which will show us all tests run from now on.
So run a batch of tests in the morning, maybe 5 minutes apart. Same for afternoon and night. I'm confident we can resolve this for you. Your patience and cooperation is appreciated.
