A complaint was registered on india post portal on 10th january 2018. Complaint number is [protected]. Since 10th jan till today 17th jan the complaint is 'still showing as pending'.
The lic office has shifted to new premise and the updated address is mentioned in the above registered complaint [protected]
The tracking report for the registered letter shows last status as lcao kolkata. No updations after that.
International calls made from bahrain to lcao office manager 'bell ringing but no one answers'. International call made to india post ivr kept me on hold broadcasting music for over 5 mins. No customer executive came on line to answer the call. Also checked at bahrain post office. Still neither the mail nor the 'acknowledgement due' not returned to bahrain due to non delivery. Need urgent help to have letter redirected to new address in kolkata.
