This is with regard to order no ORDER #[protected] for Van Huesen shorts that was placed on the 24th June and purportedly handed over to a security guard on 29th. I've kept informing you time and again that it was not delivered but receive no reply. I always thought Amazon was different. I've even ordered later a ortho mattress ( subsequently delivered) but believe me when I keep reiterating that the shorts worth Rs 779 has not yet been received by me. Why the silence to my queries/reminders?
