Delhivery is courier company name known in India few years. they get funds some where by funny 1$=75rs mode they startup here and do all nuisance disturbances in private living of every people in every country including India.
my commercial client sent a courier through this un properly managed delhivery company to me from New delhi to Tirunelveli 627001 after paying their fees .in Tirunelveli the delhivery courier person contacted me from their bala bagya nagar office and told to get the same me confirmed the timing of delivery 7 times and they accepted and confirmed but on the time they did not deliver they told to wait till evening 7pm from morning of that delivery day .the reason they told is they can delivery as they like if me cant wait it is not their fault .they are not going to suffer only we consumer paid money so suffering is for paid consumer not for un properly managed delhivery company .moreover no email id of CEO of the company is found in web and company site how to reach the true management then?
