...Maybe it's the time for concerned viewers to drop Bell ExpressVu?
The biggest problem, as I understand, is not the lack of other providers, (you can use this channel finder page to check what other providers offer EWTN in your area,) but that there are often long-term service contracts involved and the penalties are quite hefty. I wonder if it makes sense to consider a class action suit against Bell ExpressVU in such cases; after all, if they lure people into long-term contracts promising certain channels and then refuse to carry these channels - then it's nothing but a breach of promise.
Meanwhile - I'd suggest you check out the alternative providers. Some of them may have a nice promotion for those switching from Bell that may actually save you some money on the long run.
