Fast and Furious Couriers poor service

I have a parcel scheduled for delivery 2022/08/17, It then was changed to 2022/08/19. I contact the supplier and ask what is the holdup, They said Fast and Furious must be contacted and they will let me know what is happening. I logged into the suppliers web to se what is going to happen and discovered that the delivery date has now moved once again to 2022/08/22. I then contacted Fast and Furious Couriers. They indicated that there is nothing they can do as they only do deliveries on Mondays in my area. This is not true since I have seen their vehicles driving in this area on other weekdays as well. This is not the first time it happened that they just postpone as they like. I asked the call center to provide me with a number to contact the CEO, but instead they said they will put me through to the secretary's office and they can then handle the query. After holding on for 9 minutes the call is cut off. I did retry again after which the call was also cut off after 7 minutes. To add to this I got a message from the supplier that half of my package was damaged and that half of it will now only be delivered on 2022/08/29.

The service is very poor and I think the supplier must move away from Fast and Furious couriers. I make use of other courier services on a weekly basis, and have never experienced this poor service from other couriers.
