These were items dispatched by hdfc bank as part of their rewards redemption programme. The items are signoraware matt bottle qty 01 and signoraware dir glass lunch box qty 01.

I received message that the items were delivered but no it hasn’t been delivered. It’s a wrong input given by your executive.
