Unanswered emails and pathetic service

The worst courier company ever. I requested on the 15th for delivery to be rescheduled for my parcel for the 16th or 18th. Junett only responded to my email on Monday afternoon stating delivery of my parcel was rescheduled for the 18th. On the morning of the 18th I received a message the delivery failed the previous day, and my parcel was rescheduled for the delivery the 19th. How did delivery fail if I asked you to reschedule? I sent 2 emails, and tried to phone your customer service department 2 times. I eventually got through however my call was placed on hold and then just cut off. My husband phoned as well and was told a manager will be in contact with me. I am still waiting for a phone call, this is pretty pathetic service
