Sigma Couriers — Non delivery of cheque book

Address: Mumbai City, Maharashtra, 400092

My AWB no R3220377 with ICICI cheque book was returned with the reason as Door locked though courier company are suppose to leave a slip no such slip has been given and instead of delivering again received a phone call asking from which branch I can collect my cheque book . Even after that they are not bothered to deliver the cheque book . Have called ICICI bank per them it is with the courier so I will have to coordinate with the courier company and bank cannot do anything - this is the service of ICICI bank and Sigma courier -really disgusting to spend time following up for a cheque book and funniest part it is the customer who suffers
