Boot lid not opening

I bought a car from Suzuki Pinetown on the 28 January 2025 Suzuki Celario only to find out late February that boot is giving me problems sometimes it doesn’t want to open than I reported the problem to Pinetown Suzuki they said I must come to them I went there than they said they is nothing wrong the boot lid but I told them and showed the videos where it wasn’t opening okay they booked it in than they took it following day for “checking”but still even today the boot lid is still giving me problems right now I’m stucked with grocery on the boot cause it doesn’t open…….im really not happy with suzuki
