Trackon Couriers — Complaint regarding late delivery

The consignment number of my product is[protected]. It has been sent to me from Delhi to Trivandrum. Despite the courier reaching its destination point days before, precisely on 25/08/2020, I have not received the product till date. I have contacted your office in Trivandrum multiple times and they revert every time saying the courier will be reaching me the next day. but I do not find that happening either. I am extremely disappointed as a customer and sorry to inform you that this has been very unprofessional from your very part. I have never faced such an unprofessional service from any other courier service. I hope you do the needful in making my product reach me at the earliest and I also hope you work on making your services better as well.
Thanks!
