Couldn't do a simple thing on their site so phoned them. Their voice recognition couldn't understand anything I said. Eventually got through to someone who said they also couldn't do this simple thing either but would propose it (and fixing the voice recognition) as a customer suggestion by writing a note on my account. That sounded equivalent to doing nothing so I proposed making a complaint to try to advance the suggestions so they could consider improvement. Their complaints process was however a total farce with nobody at any stage able to tell me what my (very simple) complaint involved, any tangible action that might be taken to consider any improvement or to communicate by email so I didn't need to repeat everything to each new person. I got numerous 1 second phone calls then texts saying they had tried to call me. Never spoke with a single person at talktalk who sounded at all genuinely interested in customer suggestions - instead they were all very keen to close the complaint. Final person to call was from the chief executive's department - but unfortunately ruder and less interested than all the others.
