Disappointed loyal shopper

As a loyal Zando shopper, I am very disappointed with the service at the moment. I placed an my order for "winter essentials" on 08 May 2020 and to date I have not received it. When following up I was told that it would take an additional 3 - 5 days as a result of the Lockdown, which I understood however it is almost a month now. At this rate, by the time I get my winter will be over. I fail to understand how I have ordered other things online from all over the country and received them in less than a week and Zando can't deliver in 3 weeks. The frustration in made worse by the fact that you cant even track your order properly.
