You have my sympathy, this old bird, I renewed my sub with the Telegraph in February - that went through ok, then tried to renew my puzzles sub - they couldn’t/wouldn’t accept my payment …..I love my Saturday GK crossword.
It’s taken over two and a half months and numerous emails and finally !!!!! today it’s finally accepted my card etc and Saturday will be back to normal ….needless to say, no explanation or apology….talk about lack of service !!
I can understand your frustration so good luck with gaining some satisfaction xx
