I recived msg in morning about the delivery.a person having true caller id courier delivery called me and told my name and in name of derouting he said to pay 5 rupees via some (🔗http://courieractivation.site/) having name phone no UPI and after payment they assure me they are real and now just after 10 min all my account debited via someone..i took quick response and called the no. Given in informed debited message .and froze my account and everything the bank refund my amount all this process took 2 hrs almost and after that again call from different no with same voice with same message approached me .I blocked everything ..but that's not the penalty for my mental trauma and awful experience..i[censored] have no any concern regarding ur own courier then why r u doing such faulty services when u r not eligible to save ur coustomer from sacm..how the info or our details are leaked out ..how they know each small details of our products..such a worst services I have ever received...i will never gonna be use it again bluedart..
