Couriers that DONT deliver when they supposed to.

I was expecting a parcel to be delivered to me on Saturday the 07/12/2024, between 08h00 and 18h00. This was as per confirmation from this courier company. I waited the whole day not able to go out or do things that i needed to, because they cant give me a delivery time. At 18h11 on their website, it was put that i was not available to take delivery. This is a total lie as i was around ALL DAY. So it is my assumption that they decided to not do what they have been paid to do. I made contact on their whats app contact, and was informed on Sunday 08/12/2024, that they are sorry and will redeliver on the 09/12/2024. This again did not happen. This morning on the 10/12/2024, on their website they say my parcel is out for delivery. It is now 14h24 and i have attempted to get a confirmation on their whats app that they will deliver today. NO RESPONSE. And while i am typing this review i have been listening to their automated "your call is very important to us. Please wait for the next available agent" message for the past 21 minutes. I guess i should take this as a sign that this company does not deliver and ****s people. Please prove me wrong!
