Online service poor

I placed an online order on the 10.12.18,for delivery between 2 & 5pm on Tuesday. They failed on this request. I followed up on Wednesday 12.12.18 & was asked if they could deliver between 2 & 5pm,which I said was fine. Once again, they failed to deliver. I called Thursday, 13.12.18, & was asked if they could deliver between 2 & 5pm, to which I refused & said told them I wanted my delivery by 12pm. They told me that their drivers already left. I sent e mails to the V & A Waterfront branch, but to date they haven't responded. I bought often online, but I'm now totally unhappy with the service received. I even sent an email telling them to credit my account and charge DSV for the POOR SERVICE! No response to this.
