Paying for items not delivered with Sixty60 and receiving stale / rotten goods

I recently started shopping on Sixty60 and trusted each time that if they do not have an item in stock that they will bill be me correctly within 3 days for only the items delivered. The previous items were small that they could not deliver so I never checked. However, when receiving my bank statement this week, I realised the previous order's amount was exactly what I was invoices initially and the chicken was out of stock and not delivered, but I was still charged in full. The apples I ordered on previous deliveries were so badly bruised that I stopped buying apples and the last order I could only use 1 tomato as all the tomatoes in the bag were squished and rotten. The bread I received on previous orders are always by sell by date so I can basically use it for one day and then it is stale. I will not be using them in future and will rather stop at the shop so that I know what I am buying is fresh and I am paying for what I get. I did inform them about the chicken which is completely unacceptable that I paid for something not received, however no response as yet.
