The saga is over
My new friend the Bell lineman came by yesterday and found the problem. After over a month of insisting that I had a problem with the Bell wires, guess what – the problem was with the Bell wires! He swapped my line over to a spare set – hearing that nice, clear, non-fuzzy tone on the line was music to my ears. Also had a good chat with him about future issues if they come up, and importantly what to say to get service. Hooray!
