No screens available for repair centers!!!

My son bought a Samsung phone and was under the impression that if repairs needed, it will be done swiftly as it is a "excellent" brand (can't agree with it anymore). The quotation for the repair of the screen was accepted and the full amount paid on the 5th of January 2024. We got the reassurance that the phone will be ready in 3 - 5 working days. An agent from the service center phoned earlier this week to give feedback - phone not ready, will only be ready in the 3rd week of January 2024. Unfortunately we received another call later confirming the phone will only be ready hopefully first week in February 2024! I did explain that the phone is used for work / business activities. This is not an old phone, was bought in August 2023. How is it possible that Samsung deso not have ANY screens available???? Spend hours yesterday trying to get some assistance - every employee/agent is eager to listen to my story only to give me another number to phone... I've chat to an agent via whatsapp service and I need to wait ANOTHER 24 - 48 hours to get feedback. I am sick and tired of hearing "my apologies for the inconvenience caused"!!!!!! We need a screen ASAP as was promised from the beginning. Unbelievable that Samsung does not have screens in South Africa!!!
