Lenovo- terrible customer service

My work Laptop was booked in at an accredited Lenovo service provider/ repair center “Part Serve” to have the laptop shell/case replaced after a drop in January 2021. The payment was made shortly after the quote was received for Part Serve to replace the case. The laptop itself still functioned fine. 12 months later (AN ENTIRE YEAR), and after many follow ups, whereby I am continually told that ‘my case has been escalated’ I am told that the ETA has now been moved to March 2022. The ETA has just been shifted up and up and up. How is it acceptable that it takes this long to replace a laptop casing? Lenovo is supposed to be a well-renowned brand. How is this possible? The laptop was still relatively new when this happened!!!! When next year comes, are they also just going to keep on shifting the ETA until the laptop is outdated!!???😡😡😡 This is ridiculous and absolutely disgusting service. Lenovo should be ashamed!!!
