Absolutely pathetic and inconsiderate service

I've placed an order last week Thursday, 22nd Feb 2024, for an inverter due to the extensive loadshedding patterns lately, which is affecting my work. Upon reviewing sevaral deals, I've decided to purchase it online from Incredible Connection. I've checked numerous stores for pick up, which nobody had stock off according to the website. So I opted for delivery. I made the full payment and received confirmation of this. A short while later, I received an sms stating my order will be delivered on Saturday, 24 Feb 2024, and I should make sure someone is available at my home for delivery. I was fine with this due to the fact that even though I was still working, I am able to leave work as it is a Saturday and return once item has been received, but I did call in afterwards to find out if it is possible for me to pick up the item from the warehouse or any store which has stock and was instructed that I had to wait for delivery. However, no delivery was completed. I've called in on Saturday around 12pm and was advised that it will be delivered before 5pm. I left work at 1pm just to ensure I was available. However, nobody arrived. I called in Sunday morning to find out why it hasn't arrived, to which nobody had an answer for me and a complaint was lodged. I advised the lady that I was okay with delivery over the weekend as I could make myself available to be home at delivery, however, I am unable to leave work during the weekly working hours. She told me I could contact them back once delivery was confirmed and arrange for them to deliver to my work address which is literally down the road from home, however, someone will contact me regarding the complaint that we filed on Sunday. On Monday I received an sms that my item has been shipped, which I thought was already done as per the sms last week. So I called in this mojring, Tuesday, just to find out whats going on and when is it being delivered, only to be told that it will be delivered to my home address. I've made it quiet clear that I can't leave work during the week before 4pm, however, the lady did not even bother contacting the courier to find out if they could. So told the lady to either get them to deliver to my work address or she should cancel this order and I will get it elsewhere as I've planned for Saturday delivery as was instructed by sms from Courier/Incredible Connection on Thursday last week. The lady then puts me on hold and never comes back. I refuse to believe that this is the kind of service we have from retail companies. I myself have worked in retail many years ago for a couple of years and the service was impeccable. This service is so pathetic and inconvenient. I don't recommend these guys at all. For their miscommunication, I need to alter my life to accommodate their life
