I had congestion issues the last month with Primus. They were not very helpful in realizing that it is congestion and not my line, although this was obvious. I cancelled my service and switched to electronic box and am much happier.
capacity issue is what they told me after i emailed, no timeline they will able to fixed since the custom equipment haven't arrive yet and no time frame when to install it. i'll give them by end of feb before i cancelled both phone and internet services and likely switch to distributel cable 18
