Shoddy service

I ordered online and received confirmation from them on 8 August 2019 that the order was placed. However, I noticed that the delivery address was incorrect and tried to change it online unsuccessfully. Feedback later was that they were busy updating their website. This on a business day and not after hours! My order also didn't reflect on my profile and I informed them via email about the incorrect delivery address. Having had no response I phoned them but after 12 minutes of holding I left my phone number for them to return my call. Needless to say they didn't respond! A lady later responded to my email and told me that the delivery would take place today and I consequently took time off to receive it. Having sat at home all day waiting I decided to enquire about the delivery and phoned them. After about 5 minutes I again left my phone number for them to return my call which this time they did! However, it took them quite a while to locate my order as it still doesn't reflect on my online profile. This time the excuse was that the delivery truck broke down and that they could not deliver! A courtesy call to me would have sufficed!
