I am an existing customer of Hathaway broadband from September and I 2019, having account no [protected]. I am facing frequent Internet disconnection issue. Whenever I am trying to upload files to remote office server though the file size is as low as 2 MB. The internet connection get disconnected. I have raised all most 30+ tickets but it has been closed without resolution. I am very frustrated and feel like I have been cheated. Would like to have a permanent solution or would like to have refund.
