Failure to deliver

On the 18th of March, I bought an item on the Clicks online shop (surgical spirits for me and a collegue so that we can make our own handsanitiser). I selected to pick the item up at a Clicks store and I selected the store nearest to me (Worcester). After selecting the store the website indicated that the estimated time of delivery is 1 to 3 business days. After the period has passed and after tracking the package on Pargo's website, indicated that the package was delived to a courier on the 21st and there is no movement after, I sent an email. The reply was that Worcester is a remote area and therefor delivery should be between 3 to 5 days. I have two problems with that, first of all after I selected the store the website indicated 1 to 3 days for delivery. The same store is now so remote that delivery is 3 to 5 days. The second problem is, we are now on day 5 and there is absolutely no movement on the tracking website. I sent another email to which I received no reply. I tried to call the customer service, after listening to the annoying music for an hour, I hung up my phone. SInce we are going on lockdown soon, I will not recieve my package in time and I actually think that I am not going to receive it all.
