Extremely Dissatisfied

I initially logged a return on 9 October 2025 on reference: MRRN-ZM6DW-WNYV for a faulty device. After 2 weeks with the supplier, the device was repaired and returned on 25 October. After a few days of using the device, a return was logged again on 30 October 2025- as the device would not charge. refer to new reference: MRRN-WZ8P7-JEDJ. It is now 7 weeks since 9 October and I am still without my product. I have made numerous calls to the service center and sent numerous emails as well. Each response I recieve is generic and does not address the problem, when am I going to receive this device?? I called this morning and was told a manager is going to call me.
