I have been a customer since 1995, with the same home address. Up until about a year ago the signal was either 3 or 4 bars, and we rarely lost
calls. The signal started diminishing then, and now I am lucky if I get 1 bar. We lose calls al the time. This is a real issue. Did something happen to a tower?? Our phones are reasonably new. This should not happen.
Please advise what can be done.
