Online Delivery - DELAYED...... AGAIN

I ordered a pair of shoes on Friday the 23rd of September that was scheduled for delivery in 2-3 days. I received a message form their logistics partner "Pargo" that the package will be delivered on Tuesday the 29th of Sep. On their tracking app, it was suddenly changed to Wednesday the 30th. Then I received a message at 4 pm, stating that the delivery could not be made on the 30th with no explanation. When I tried to find out from Pargo what the reason was, there was no information provided. I was informed to contact Cape Union Mart directly. When I eventually got to speak to a consultant, I was promised that it would be delivered before 12pm today the 1st of October. I contacted Pargo at 12:01 since the package has still not yet been delivered. I was informed that they "try" to resolve... I am very disappointed with the service I have received. I would have thought that in these times the companies that offer online shopping, would have streamlined their processes and communicate better with their clients.
