Qatar Airways: poor customer service

I flew from Johannesburg to Doha, then Doha to London Heathrow, arriving on 11th October 2022. Unfortunately, I left a trolley bag (presumably) on the carousel, as my wife and I forgot about the extra bag altogether. When we realized, later that day, we made every attempt to try to locate it, and retrieve it. Despite numerous calls and emails to Qatar, and promises of 'escalation' and replies within 24 or 48 hours, it seems that they did nothing to try to locate my bag, and made no attempt to try to help me - I had three months worth of medication in that bag, plus three pairs of shoes, jewellery, etcetera. It was entirely my own fault - but I am terribly disappointed that Qatar Airways has such poor customer service. If I knew that the bag had disappeared altogether, that someone had taken it off the carousel, and it was gone, forever, I could accept it. Now, I have given up all hope, and have little confidence in Qatar Airways...
