Terrible customer service. I had bought a £245 set of 5 phones and they had a 2 year warranty. All phone calls go to a voicemail system, so you can't speak to a real person. Online repair form filled in and returned and I was called back, being promised a freepost envelope for the non-working item 1 year into the warranty. Nothing. I called back leaving a message for a supervisor to call me back. Nothing. I called them and left them a message saying I had been promised a return envelope, that no-one had called me back, that their telephone communication and email communication was terrible and could they call me back and resolve things. Nothing. I called and told them I would be reporting them to trading standards. I then called Siemens who answered immediately, have given me a call reference, and will be sending out a freepost envelope.
