I paid to upgrade my DSL service through TDS Telecom. The upgrade has made my service worse. I paid for 760Kbps service prior to this and thought I could upgrade to 4Mpbs service for the same price. It turns out that the circuit they changed me to is longer (nearly at the practical limit) from my house to the DSLAM. The result is that I paid to upgrade and ended up with worse service. Not done trying to fix it, but it may mean moving to a new, altrenative provider.
