I love this type of thread...
The OP had a flight cancelled (and an alternative offered) because of a strike (which he doesn't say was by BA staff or other people). He wasn't happy with that and complained (the response to which did seem rather slow, I admit).
Three months later he throws his toys out of the pram and tells BA that he'll never fly with them again. He is surprised that they don't respond (what did he expect? A minibus of nubile BA cabin crew on his doorstep?). But proudly, he tell us that he has managed to spend all his BA miles. Well, bully for him...
Another poster gets sniffy when his assertion that "we all know" that BA is not interested in customers is challenged.
The reason why I love these type of threads? It's because they all share this trait of extrapolating from the particular to the general. And because the posters usually sound so pompous about the whole thing...
