Respected sirs
I have send some food items to my wife who has been working in mumbai through st courier from alleppey on 24 the october 2019. They have charged me 600 rs for 5 kgs. And they have promised me the item will be delivering in three days. After 4 days i have contacted them they appologise and said their flight has delayed they deliver the package. After 7 days i have asked them again from their outlet and they said the item reached in mumbai tomorrow it will deliver. At last today 1st november 2019 they have delivered the package to the security guard. When i recieved the package i have noticed that the package has been cut off by rat. All of the food items has been eaten by the rat. And i throw the item to waste bin. Sir courier system in our country is very poor.
Sir i would like to complained here about i need the money back i have spend food item cost 1000 rs and shipping charge 600 rs
Yours faithfully
