Infuriating

Ok I ordered something for a birthday party so I chose the same day option used my work address since I did the order early before 10am thinking it would definitely come before I leave work at 15:45 and then I added in something for myself aswell. I kept on trying to track my order but it seemed it Was not going anywhere so I phoned the call center explaining that the latest I can receive my order is 15:45 the lady assured me that she will escalate it wile I'm on the phone and she did and assured me I'll get it before 15:45 I kept on following the delivery online and it was moving so I felt assured it was going to be delivered in time then when it went past 15:15 I got very worried and phoned again the lady checked and also phoned the delivery guy she told me that he has two more addresses to go to and won't be in time for me I told her but I said 15:45 for a reason I had to leave work at that time to pick up my kids so I told her in that case she must try make a plan and she said the delivery guy should be there at 16:30 then I said please cancel the order cause I won't be at work at that time. Then at 16:45 I get a call from the delivery guy saying I can come get my delivery I told him I'm not at work anymore asked for the delivery tothave been done at 15:45 and that he can take the things back to takealot. This morning I check on the dilivery schedule it say I refused delivery. So not true I ask for it to be at the delivery address at a certain time I was assured it would be and it was not. Infuriating
