Hi there, karic19. Thank you for posting in the community for support. We are sorry to hear about the trouble you're experiencing with your internet speed, we know issues of that nature can be very frustrating. We understand that on top of that, you also have concerns about the charge you mentioned. The last thing we want to do is to make you feel taken advantage of! We typically don't charge for service calls when the source of the issue is Comcast-related. This is going to be up to the technician's discretion. As an example - if we came out and determined that the cause of the slow speed is your equipment , that is where that $70 charge would come in. We do recommend this link being used to run speed tests, for accuracy reasons: https://speedtest.xfinity.com/. We do also have the ability to pull up your speed test data on our end if that link was used, when you reach out to customer support. May we ask you what the technician mentioned as the source of your speed concern?
