Dell non-warrantee despite contractual obligation

I booked repairs this Tuesday, ***, and the repairs were scheduled for this Thursday at my place of work. Thursday came and nobody contacted me or arrived, so I contacted Dell - they rescheduled for today at my home address. Today came and they claimed ticket *** did not exist - until I sent them the screenshot - then magically it existed again, but was linked to someone else with a different address and contact details...apparently. I have now spent almost 2.5hours today getting a new ticket for Monday, and have subsequently lost 4 days worth of income. Dell claim to have a no compensation policy while admitting to being in breach of their warrantee policy in jy case. They are clearly trying to avoid honoring my warrantee which is still valid until September 2025 - whatever you do - never buy Dell. No only can I not get my warrantee honoured but my work laptop keeps restarting itself over and over - rendering me unable to work - absent compenation. No honesty, no integrity, no service
