BAD SERVICE DELIVERY

after being buzzed and me answering the phone I called ccd couriers to arrange for the delivery of my parcel.I was expecting to receive my order on the 9th of march 2021 only to receive an sms that states that there are delays and the contact center will contact me to reschedule for delivery. Only on the 10th of march 2021 I receive a text stating that I had missed my delivery and ccd has been unable to reach me to reschedule for the delivery which is a lie, I then called the contact center again only for the them to tell me they don't know what happened and they are escalating the issue. I further received a call from the ccd couriers consultant an hour later who told me she is still going to escalate and she didn't know what was going on with my order.So now im being sent pillar to post where no one knows what is happening with a parcel that is with them. how many escalation do the ccd couriers need to do in order to find the parcel that is in their system and have the decency to call back instead of them buzzing my numbers and sending endless sms with lies. This is beyond *********** cause clearly people don't know what they are supposed to be doing.
