Poor customer service

I made an online purchase on Monday which I was supposed to receive yesterday I however did not receive it. The day before I got an email from clicks stating that my package has been dispatched and it's on the way about an hour after that email I receive another email from Clicks Omni Channel stating that my package will be an extra 2 days late due to their mistake during stock take. I immediately sent an email which I didn't even receive a response to about this issue and how disappointed I was with the customer service they provided. I'm still not certain on my package and I also mentioned that I have medication which I urgently need.

This is honestly sad as I'm a loyal clicks customer and this is not my first online purchase. But if this is how they'll be operating I don't think I'll be purchasing from them in the future.
