UPDATE 22 FEB 2023 After struggling with these people for a month I sent them a stiffly-worded note for the attention of the Service Manager. Things went quiet for a fortnight (they are VERY SLOW thinkers) but today the very same dingbat came back with EXACTLY the same email, asking the same stupid questions as a month ago. Today, I am writing AGAIN to the Company Secretary to remind him that they have all the information to deal with this warranty claim. DON'T BUY SHARES IN THIS LOSER COMPANY.I have one of their most expensive mice which has developed a sticky switch under one button. The Bot was eventually persuaded to put me through to an agent who from his behaviour was also a Bot. From his name he appeared to be based in South-East Asia. He insisted that I do some prescribed tests and I told him to stuff it - a sticky switch needs a return authorisation and number, not further uninformed time wasting. I told the second Bot that I would write to his head office and to send me a copy of the Chat and he had the temerity to tell me that their policy does not allow that. I hope that Logitech.uk read this, because they will also be reported to the Data Protection Commissioner.
