Delivery keeps changing

I placed an order with TakeALot for delivery 01/06/20. I got x2 SMS on on 27/05/00 and on int he morning on 28/05/00 stating that my order would be delivered before 17H00 which I was pretty impressed about.

17H00 came and went with no delivery, I then got another SMS saying they tried to deliver but couldn't (This is strange as I was home all day), Last night I got an SMS stating that they would deliver 29/05/00 before 15H00

I have now just received an SMS stating they will deliver before 15H00 on 01/06/00

You guys are messing me around and I can''t even contact anybody as your phones are all down with your staff working from home.
