How about providing a telephone number that one can can to report a fault that does just loop back to where you started?
How about putting customers before profit and make it not just easy, but POSSIBLY to contact you.
How about having a proper complaints code with real live chat option rather than just pretending to and just taking you to a series of irrelevant topics.
How about thinking about becoming a decent properly run organisation. My elderly parents (mid eighties) have now had no working phone for 3 days yet it's IMPOSSIBLE to contact you and an email complaint was just bounced straight back.
TalkTalk, a Disgraceful, useless company.
