Was expecting courier from bank last week. Sandeep incharge person at sigma courier, vashi branch promised it will be delivered today. Same was not done after sever follow ups.
His contact no [protected]

He is highly unprofessional. So do sigma courier service is pathetic n i dont think pathetic servicing will sustain competition. Such courier service must be shut
