Urgent Complaint Regarding Unresponsive After-Sales Support

I am extremely disappointed with the complete lack of after-sales support. Despite submitting multiple support tickets and making repeated phone calls, I have not received a single response. The absence of any acknowledgment or assistance is unacceptable and reflects a serious failure in customer service.

If this is not resolved immediately, I will be terminating my relationship with your company at the earliest opportunity and will not hesitate to share this experience publicly.
