Poor Online buying experience

When you get to a website, in the modern day and age. And you attempt to log into your "online account" and for some reason it doesn't work. So step 2 is to reset your password, under "forgot my password" (email send, go into website, create a new password....)

And here is the best part. Your newly created password doesn't work. How hard can it be to have a proper IT system and website? So, ultimately the problem is, I have 2 items, in my basket that I would like to buy online as it is an "online exclusive" sale and yet... due to Clicks neglect and errors I can't even buy it. Truelly disappointing, as an customer of clicks for over 8 years
