Dear sir
I have ordered an product on amazon with tracking id
[protected] and[protected] but this is third time issue with from your side that your courier partner not delivered my product mark false review in system and today my product is return to amazon just because of your worst service before this i already lodged an complaint in 10 june 2020 but still no action has been taken on courier partner of jalgaon jamod. On that time i already mailed an call recording in which courier delivery boy directly told that he is not delivering my product just because of his personal issue..

It is continousaly happenig that just because of his personal issue he was not delivered product in my area if you didnot need custmer then close your service in my area because your just waisting time...
They did not contact me if i contact then black list my number

This is last humble request kindly do needful action and give me proper resolution because after 3 month you did not take any action and not provided any resolution against my complaint.
I hope this time i get proper resolution from yo
