Its been 4 days since the package is just staying in their warehouse.
I was not present during one day when it was sent for delivery, its been 4 days since and they take no action.
Their email takes hours to respond, and that too they reply vaguely.
And i have not been ever able to use their customer service number.
So effectively there is just no clear way to contact them, and they just want to hold onto my product for god knows how long
