No info regarding online order

I placed my first online order and everything went smoothly. Then on Monday (3 September 2018) I placed my second online order. I needed to purchase glucose sticks for a family member and Clicks states that it'll take 1 - 3 working days for the order to arrive. I placed the order on a Monday knowing the glucose sticks would be finished Saturday (8 September). I sent an email on Friday 7 September but got no feedback just an automated response. And then was forced to phone the sharecall number on Saturday to find out about the order. They can't help me, they can only log it so someone gets back to me on Monday regarding the order. I also mentioned that the online contact form on the website isn't working but the person I spoke to didn't have any idea what I was talking about. Disappointed and concerned about the lack of glucose sticks for my family member
