Bad Service

I bought a Samsung A03 Core from Ackermans Khayelitsha on Thursday 22 December 2022 at 18:02 and the device is overheating, also responses are mostly delayed. I took the device back today on the 7th day and they telling me it's out of warranty, the manager Sithembiso Sigadi refused to give my money back and the consultant who helped me Mihle Mente admitted she said its 7 days warranty but she assumed i knew its 7 days from point of purchase, now when i calculate exact hours from the 22 December at 18:02 till 16:10 on 29 December 2022 that is 6.91 days and i am still in time to return the device. Thursday to Thursday is also 7 days regardless of counting the hours and still even if counting hours it makes 6.9 days of which i am being wronged. I am so disgusted with their service and i will follow through with my complaint and i hope Jaap Hamman as the Ceo takes note of this as this is terrible service.
