Trackon Couriers — intolerable language used by the office head

Since 2 days are courier is lying in the office and they are not delivering it. When we call it that talk very badly, that to with the lady that don't have any sense how to talk. If they are so much flying on seven sky, let them know that they are not the only courier company. They dont delhiver parcels on time and when cross questioned, talk very rudely. Its gole market office, rudrapur, 263153. Just first teach them mannerisms to talk with a lady!
