Clicks - Bad Service

I did an online purchase with Clicks on the 1st of July 2020 for store pick up, their site stipulates delivery time as 1-3 working days however this wasn't the case, I then contacted their customer services via email, I have actually sent numerous emails to clicks and they have not given me a single response. I then called customer services on the 10th of July 2020, a consultant advised me that their courier services is delayed and my order will be at the store by Monday (13.07.2020), I had to call customer services again today, 13.07.2020 only to find out their courier services picked up my order on the 7th of July 2020 but never delivered it to the store and they no idea why, this was never communicated to me in all this time that I have been querying the status of my order, Clicks just ignored every mail I sent to them. All items purchased are necessities and Clicks has no urgency at all in having these items available for me to collect. I then asked the consultant to get the store to put my order together and the consultant advised that they don't work that way, the items are sent from Jhb so Clicks expects me to wait longer for my items to arrive in Dbn. This is really ridiculous!!
