Treeable service for Internet Express

No care for customers or customer service, my package should have been delivered today friday the 01/12/2023, after about call the contact number 10 times and sending a email I finally someone answered my call and when I gave the agent my waybill number they informed me that my package would only be delivered on monday ? after the tracking page of their website site said that it would be delivered friday the 01/12/2023 and the problem was that they had a system error/delay this is unacceptable as other courier companies have back up plans, I wasnt even notified nor is the a notice on your site that there is delays and when I asked if i could come and collect my package I was informed that I would need to come the next day? this is totally unacceptable and I will not use there services nor would I recommend them to anybody, I understand that there are delays and things happen but not to inform people or not putting a notice on your site of delays is unaccpetable
