Worst no service

I called Dell India 21 Feb 2023 and was referred to Ensureit service Midrand JHB, I paid R450 and handed my laptop to them 23 Feb. Today is 7 March, I have had no reply via email or text. Every day since 3 Feb I call Ensureit services 3 times a day and speak to them for 45 mins a day. I often get put in hold and cut off, no one bothers to call me back. The Customer service manager Kelvin Pillay, tells me not to worry and commits to calling me back but he does, I called him 6 times and he cut me off on his mobile. Lloyd Branch manage is not available, Tech manager Manugaul not available. Everyday, 3 times a day I speak to Lethabo, Rosslyn and Kelebogile and I get no help. WHAT DO I DO ???? I have call Dell India and was transferred back to Ensure it services again. Does Dell International know that SA does not help clients ? Can someone pls assist me, I have not done work since 21 Feb, problem with my hard drive.
