A week ago, on Wednesday, an OR engineer came to the house. I had told AA that as before the fault would get magically fixed by the engineer, despite him not doing anything other than testing the line. And indeed it was so, line fixed, perfect, but the fix only lasted from Wednesday to Saturday, a record short duration; usually a magical fix holds for many weeks or months. I clearly could not ask AA to ‘repair’ it again so Plan B was initiated, that is, getting new lines instead, hopefully.
